Key Takeaways

  • An AC breaker can trip if it is overloaded with many appliances, if there is a short circuit in the unit, or if the breaker is not sized properly.
  • Dirty and faulty components in an AC can often cause a breaker to trip frequently. It is also possible for a malfunctioning breaker to be the culprit.
  • Electrical faults are very dangerous and you should not attempt to fix them yourself. Hence, always consult with an HVAC professional.

When the AC is tripping your electricity, it’s important to pay attention and quickly diagnose the problem.

As an experienced HVAC professional, I know all the common issues that can cause your AC system to trip the breaker.

I’ll share my knowledge and help you get your air conditioner running again quickly.

13 Common Reasons Why Your AC Trips The Circuit Breaker (Solutions Included)

AC electrical faults cause 86% of dangerous air conditioner fires[ 1 ], and circuit breakers help you stop that from happening - but only if you know why it’s happening and what to do next.

1. The Sizing Of The Breaker Is Improper

Circuit breakers are rated by amp s , determining the amount of current that can flow through without tripping the breaker.

The average home circuit breaker is 15-20 amps for the branch circuit , which is plenty for most home AC units, but larger air conditioning systems using too many amps can cause the circuit breaker to trip[ 2 ].

You can either:

  • Move your air conditioning unit to a different place/room with a larger AC circuit breaker,
  • Hire a professional to upgrade the breaker and accompanying wiring.

TL;DR:  If rated amps of a circuit breaker are lower than the rated amps of the AC, it will always trip.

2. You Are Overloading The Circuit

Each circuit breaker can only handle a certain amount of amps.

If you have other devices running through the same circuit breaker as your air conditioning system, it can o verload the AC circuit breaker and shut off your power.

Reroute other electrical devices so your AC unit can run through the breaker independently. You may need a professional to help.

TL;DR: A dedicated circuit is recommended for an AC. If too many appliances are connected to the AC circuit, it can get overloaded resulting in breaker tripping.

3. There Is A Short Circuit With The Electronic Components

ACs have internal electrical components that run continuously for hours.

Over time, the wires within the air conditioner can become damaged, leading to a ‘short’ (or short circuit)[ 3 ].

A 'short' means too much electricity is flowing through the wires and can cause overheating and fires.

The air conditioner circuit breaker will trip to shut off power and protect your home from danger.

You need to contact a professional to find the source of the short circuit and make appropriate repairs.

Electrician Fixing AC breaker

TL;DR: A short circuit is a very dangerous condition as it is a sign of damaged electrical components. Seek professional help if you suspect this is the case.

4. A Dirty Air Filter Heating Up Your AC

The air filter in your AC unit will get dirty over time as air flows through the machine (more so with an outdoor unit than an inside unit).

If the air filters become too dirty, they can reduce airflow and cause your air conditioner to overheat, as the electric motors must work harder.

Your air conditioner will try to draw more power to compensate for the poor airflow, tripping the breaker.

Change or clean the dirty air filter to stop your AC system from tripping the breaker.

You should be able to replace the air filter and perform regular maintenance yourself.

Important Note:

It is crucial to point out that you should avoid DIY maintenance if you have the slightest hint of doubt that things may go wrong. To avoid harming yourself or damaging your unit, always consider hiring professional help. 

5. Dirty Condenser Coils Can Also Heat Up Your AC

Your condenser coils absorb the heat from the air, but they can become blocked by dust or debris (particularly if you have a dirty outside unit).

The dirty coils can strain your air conditioning system, causing it to work harder and draw more electricity. 

They may lead to it tripping the breaker.

Cleaning dust and debris off the dirty condenser coils should stop the AC tripping.

You should also have an AC technician check and perform annual maintenance on your condenser.

TL;DR: Dirty filter and dirty condenser coils can heat up the internal components. Higher heat results in higher current draw resulting in your breaker tripping. Perform regular cleaning of these components.

6. Problem With Coil Fan Motor

Air conditioners use a coil fan (or AC blower) to move hot air over the condenser coil and disperse heat, leaving you with cold air.

Your coil fan can become damaged over time , and a broken coil fan can cause the AC to draw too much power, leading to the breaker tripping.

Hire a professional to perform AC repair work on the coil fan motor. It may need to be replaced to stop the breaker tripping.

TL;DR: A broken coil fan motor can draw more than its rated current, which in turn can trip the breaker.

7. Your Compressor Has Gone Bad

Your compressor houses the refrigerant that cools the air, but a faulty compressor won't cool the air.

Faults become more common as a compressor ages but can happen because of accidental damage.

A bad compressor can cause two issues:

  • Hard starting.  Your faulty compressor won't start up properly and draws more power to try and compensate, causing it to trip its own breaker.
  • Grounded compressor. The wires connected to the compressor come loose, leading to a short circuit and a tripped breaker.

A technician can install a hard start kit to try and get the compressor started.

However, a faulty compressor can mean costly repairs, and it's often best to replace the entire system rather than try to fix it.

Air Conditioner Compressor Outside a Room

TL;DR: If the compressor is hard starting or if it is grounded, then it will draw far more than its rated current.

8. Cables And Wires Wear And Tear

Your AC runs has wires running inside the whole unit connecting electrical components.

Over time, the wires and wire insulation can become loose or damaged.

Loose wires touching the ground, floor, or other components can cause further damage to the device and your home.

The circuit breaker trips as a safety measure to avoid an electrical short and prevent damage.

Some electrical wires can be an easy fix, but electrics can be dangerous.

Have an HVAC technician check the electrical panel of the unit, find the damage, and perform the AC repair safely.

A loose wire or a grounded wire is a dangerous safety hazard. You should avoid touching or going near the unit if you spot a loose connection.

9. Too Little Refrigerant

Refrigerant is the working fluid in an AC unit that cools the air.

The AC compressor has a closed system for the refrigerant, but over time, refrigerant lines can become damaged.

This damage can lead to refrigerant leaking out.

The AC compressor coils will have to work harder to cool the air if there's less refrigerant.

The unit draws more electricity to compensate, which trips the breaker.

Hire a professional to top up the refrigerant and seal the leak.

However, it may be cheaper to replace cheaper portable ACs than perform the repairs if it's out of warranty.

Refrigerant is a dangerous substance and can only be handled by professionals.[ 4 ]

Refrigerant Charging for AC

TL;DR: Lower refrigerant means that the AC has to work harder in order to cool. This in turn means using up more amps to compensate. More amps = breaker tripping.

10. Frozen Evaporator Coil

Dirt, debris, and grime can build up on the evaporator coil, preventing heat from flowing and causing the coils to freeze.

The air conditioner will try to draw more energy to compensate for the frozen coils , but as it draws more amps, it can cause the breaker to trip.

You can fix this yourself by turning the power off and thawing out the compressor using a hair dryer.

Once dry, clean the evaporator coils to prevent them from malfunctioning and freezing over again.

If your air conditioner keeps tripping after this, contact a professional to determine the root cause.

11. It’s Too Hot Outside

Your air conditioner has to work harder in hot conditions to maintain the temperature, which can cause it to draw more electricity and strain the wiring.

It can also cause the breaker to trip to prevent overheating or fire hazards.

Clean the AC to keep the unit cool by improving airflow, and only use the air conditioner when needed.

If it keeps tripping the breaker, you may need to buy a new AC.

TL;DR: If the internal components are heating up due to very hot weather outside then this can lead to the breaker tripping to avoid fire hazards.

12. Failing Air Conditioning Capacitors

Your AC capacitor provides the initial jolt of electricity so it can start.

Capacitors wear out over time, and if you notice your AC has trouble starting or keeps tripping, the capacity may be failing.

Contact an HVAC professional to fix or replace the bad capacitor.

13. You Have A Defective Circuit Breaker

A circuit breaker can become defective through natural wear and tear, exposure to extreme temperatures, or by electrical faults tripping the breaker too frequently.

A defective breaker can trip your electricals every time you use your AC.

First, make sure the breaker is actually defective. 

Circuit breakers trip electrics and protect your home, a nd you should only replace them as a last resort.

If you don't resolve the issue, the new breaker will continue to trip.

Check the other common causes on the list or consult an HVAC technician to determine the issue. A professional will need to replace the circuit breaker.

TL;DR: If all else is fine, then the likely culprit is a defective breaker. Most homes have a spare breaker which you can switch your AC to. If not, then a breaker replacement will be necessary.

When To Call Professionals For Maintenance Or Repair

I recommend calling a professional to help with most air conditioning electrical problems because it can be dangerous.

Always consult a professional if you experience any of the following:

  • 1 There is a burning smell from the breaker or AC: A burning smell indicates that your electrical wiring or AC breaker is overheating. It's a dangerous fire hazard, and you should shut off the air conditioner and contact an HVAC technician immediately.
  • 2 There are crackling or electrical sounds from the breaker or AC: Strange noises from your inside unit usually indicate an electrical issue, loose wiring, or short-circuiting - often in the compressor motor. It is dangerous to fix yourself, and you need to contact an AC Tech professional to undertake air conditioning repair work.
  • 3 You cannot point out where the issue lies: Your AC breaker trips the electrical supply for a reason, usually to protect you from serious danger. If your unit is tripping the AC breaker and you can't find the issue, you need to call an HVAC technician as soon as possible to diagnose the problem.

TL;DR: Electric works should always be carried out by professionals. However, some very alarming signs such as burning smell and crackling electrical sounds call for an immediate inspection. Shut off your home's main electric breaker if you experience these signs.

Why is my AC's circuit breaker tripping?

What type of breakers do AC units use?

Air conditioning units typically utilize circuit breakers that are designed to handle the specific electrical requirements of the system. Here’s an overview of the types of breakers used:

1. Double-Pole Breakers (most common in Florida)

Many central AC systems require a 240-volt circuit, which is usually controlled by a double-pole circuit breaker . These breakers are designed to handle the higher power requirements of an AC unit, and they control both the hot wires in the circuit, ensuring that the entire circuit is shut off during an overload or short circuit.

2. Ground Fault Circuit Interrupter (GFCI) Breakers

While not commonly used for central AC units, GFCI breakers are sometimes found in mini-split systems or window units, especially in damp locations. These breakers provide protection against ground faults by rapidly cutting off the power when a leakage is detected.

3. Arc Fault Circuit Interrupter (AFCI) Breakers

These are designed to prevent electrical fires by detecting an unintended electrical arc and disconnecting the power before the arc starts a fire. Though not typically used solely for AC units, they may be part of a home’s overall electrical safety system.

5. Time Delay Breakers

Air conditioners often require a significant surge of power on startup. A time delay breaker  allows for a momentary spike in electrical demand (inrush current) without tripping. This type of breaker is particularly useful for systems with compressors and motors that have high startup power requirements.

Why is my AC's circuit breaker tripping?

Where is my AC circuit breaker located?

The location of your AC’s circuit breaker can vary depending on the design and layout of your home or commercial building. Here’s where you might find it:

1. Main Electrical Panel

Most often, the AC’s circuit breaker is located inside the main electrical panel or circuit breaker box. This panel is typically a metal box containing various circuit breakers for different parts of the building. It might be found in the following locations:

  • Garage : Many homes have the main panel located in the garage.
  • Basement : If you have a basement, the panel might be located there.
  • Utility Room : Sometimes, the main panel is in a utility or mechanical room.
  • Exterior Wall : In some cases, especially in warmer climates like Tampa Bay, the panel may be mounted on an exterior wall of the home or building.

Why Does My Central Air Conditioner Keep Tripping the Breaker?

why breaker trips on ac

The last thing you want on a sweltering summer day is to have your air conditioner keep turning off because the circuit breaker keeps tripping. Your home’s circuit breaker is a safety measure that protects against damage from overloaded circuits, which could cause a fire. Your AC constantly tripping your circuit breaker means that it’s pulling in too many amps than the breaker was designed for.

This is a problem that you definitely need to address before it gets worse. Don’t just keep resetting the circuit breaker. You need to see an AC repair specialist immediately in order to prevent further damage and potentially dangerous situations.

The first thing you should do if you’ve noticed a problem with your AC circuit breaker is to make sure there really is a problem. If there was a recent storm or power outage, the circuit breaker might’ve been tripped in a one-time power surge. 

However, if the problem has happened more than once, it’s likely an issue with your AC system. You might be able to simply reset your air conditioner’s internal circuit breaker. Take the following steps to do so:

  • Turn the AC system OFF (on the thermostats)
  • Reset the AC circuit breaker switch in your electrical panel to ON
  • Wait 30 minutes with the air conditioner OFF
  • Set your air conditioner back to COOL

If everything works as it should after this reset, you’re good to go! However, if the AC circuit breaker immediately trips again, or if it won’t turn on at all, you likely have a problem that needs to be looked at by a professional. If the AC system works for a little while before turning back off, there might be something you can do to fix it. 

Call Your Trusted Toronto HVAC Professional

Your air conditioning system is a large investment, one you don’t want to risk by accidentally breaking something even further in an attempt to fix it yourself. While there are many maintenance tasks that are easily accomplished by homeowners, an electrical issue is something best left to an AC technician with the knowledge, skills, and qualifications to handle it.

If you’re unsure of what the cause might be, the best way to ensure peace of mind is to contact your local HVAC technician for AC repair . A certified technician will be able to walk you through any possibilities, help you troubleshoot, and determine if the issue is something minor that you can fix yourself, or if it will need to be professionally serviced.

8 Reasons Your Central Air Conditioner Keeps Tripping the Breaker

1. dirty condenser coils.

If you’ve been neglecting your yearly AC unit maintenance, you might’ve noticed that your home isn’t as cool as it should be. Dirty condenser coils might be the issue, and luckily it’s one with an easy fix.

When your condenser coils get dirty, they lose their ability to disperse heat. This can lead to the air conditioner overheating, which may be the cause of tripping the circuit breaker. 

Dirty coils are usually caused by a buildup of dust and debris on the outdoor unit. Make sure you’re doing your yearly cleaning—and scheduling regular tune-ups—to keep the condenser coils in good condition.

2. Dirty Air Filter

Dirty Air Filter

Dirty filters may cause your air conditioner to trip the circuit breaker. Reduced airflow means the fan motor must work harder and longer to draw air through the filter. This can draw too much electricity, causing the air conditioning unit to overheat and resulting in an electrical short.

If you’ve noticed puddles of water around your outside AC unit or there’s no cool air coming from your AC , it might indicate restricted air circulation, which might be the cause for why your breaker keeps tripping. The easiest fix for this is to change the dirty air filter. Air filters should be cleaned and changed regularly , depending on how often you use your AC.

3. Old Air Conditioner

Nothing lasts forever, and your air conditioner is no exception. If your system is over 10 years old, it’s probably nearing the end of its useful life. The time will come when the cost of extensive repairs to keep an older unit running is more than it would cost to replace it with a new AC unit . 

Older units will show signs of failure before they break for good. If the air conditioner’s circuit breaker tripping is only one of many issues you’re seeing, it’s time to consider replacing your unit. 

4. Faulty Fan

Your AC system uses fans to help move air around, blowing over the coils to release the heat from your inside unit. If the motors that run these fans are damaged or dirty, your AC system will be using more energy, which might be the cause of your AC breaker trips.

If the fan blades are coated in dust and debris and slowing down the fan, a thorough cleaning might be enough to fix the problem. However, if the motor that runs the fan is malfunctioning, an AC technician will have to replace the motor.

5. Frozen Evaporator Coils

When maintenance is neglected, problems start to build up. Eventually, airflow is reduced, which causes the AC evaporator coils to freeze up . If you’ve had issues with your AC tripping the breaker, and if you see ice on the coils of your AC unit, it’s best to keep the system shut off and call in a professional. Keeping it running might result in compressor failure, which is a much worse problem to have.

6. Compressor Issues

Compressor failure is a serious issue that may require a whole new system. As the heart of the air conditioning system, your compressor pulls in lots of power when it starts up. As a compressor ages, it will have trouble starting, which pulls in even more power and can result in circuit breaker trips.

If you have a grounded compressor, that means electrical wiring inside the compressor has broken and is touching the side. This causes a direct short to ground, and usually, this will ignite the oil, causing a burnout. A faulty compressor means you’ll have to replace the AC unit altogether. 

7. Refrigerant Leaks

If you have an older AC unit (especially one that hasn’t had regular maintenance), corrosion can develop on the coils. This can lead to cracks and holes in the refrigerant lines, which will cause a refrigerant leak. When the refrigerant pressure drops, air conditioners have to work harder to cool your space. As a result, the unit will draw too much power and cause breaker trips.

8. Loose Wiring

There are plenty of wires connected in both the outdoor and indoor unit of your air conditioner that keep things running. Any of these wires might become loose or lose their connection, and this can cause a short circuit, resulting in a tripping breaker. 

Wiring issues are best left to an AC tech. They can re-wire any faulty circuits and replace a bad circuit breaker.

My AC Breaker Keeps Tripping: Common Culprits and How to Fix It

AC breaker keeps tripping what to do

If your AC breaker keeps tripping, it can be a frustrating and confusing problem. If your air conditioner is tripping the breaker, there can be a range of issues behind it, such as a dirty air filter, dirty condenser coils, fan damage in the outdoor unit, a faulty compressor, damaged or loose electrical wiring, or a bad circuit breaker.

You might not know what’s wrong with your AC circuit breaker or how to fix it. Don’t worry – we’re here to help! The  Cincinnati air conditioning repair  experts at Thomas & Galbraith Heating, Cooling & Plumbing team will explain what an AC circuit breaker is and why the breaker trips. We’ll also share how to troubleshoot certain issues that may be tripping the breaker and when to call an HVAC professional to fix AC units.

What Is the Air Conditioner’s Circuit Breaker?

A circuit breaker is an electrical switch that automatically turns off when the current flowing through it becomes too strong. This prevents damage to the circuit by preventing it from overheating.  Circuit breakers  can be found in homes, businesses, and industrial facilities.

They are typically located in the main electrical panel, which is typically located in the basement or garage. Circuit breakers come in a variety of sizes and amperages, and they can be either single-pole or double-pole. Single-pole circuit breakers are typically used for small appliances such as toasters and hair dryers, while double-pole circuit breakers are typically used for larger appliances such as ovens and  air conditioners .

When choosing a circuit breaker, it is important to select one that is rated for the amperage of the circuit it will be protecting. For example, a 20-amp circuit should be protected by a 20-amp breaker.

Circuit breakers can trip for a variety of reasons, including overloads, shorts, and ground faults. If a circuit breaker trips frequently, it may be an indication that the circuit is overloaded and needs to be replaced with a larger one. Short circuits occur when there is an accidental connection between the hot wire and the neutral wire.

Ground faults occur when there is an accidental connection between the hot wire and the ground wire. Both of these conditions can cause overheating and damage to the circuit breaker, so it is important to have them repaired as soon as possible.

Why Your Air Conditioner Circuit Breaker May Trip

A circuit breaker is designed to trip and cut off the power when it senses an overload on the circuit. This is a safety feature that protects the wiring from overheating and starting a fire.

However, if the circuit breaker is faulty, it may trip even when there is no overload. This can be frustrating, especially if it happens on a hot day when you are trying to use your air conditioner. Here are some of the common reasons your air conditioner may be tripping the circuit breaker.

Dirty Filter in the AC System

A common cause of the air conditioner circuit breaker tripping is dirty air filters. The air filter helps to remove dirt, dust, and other airborne particles from the air as it circulates through the system. Over time, the filter can become clogged with debris, making it harder for air to flow freely. As a result, the air conditioner has to work harder to cool the home, causing a rise in electricity usage. This increase in electricity usage can cause the circuit breaker to trip, disrupting the flow of power to the system.

If your air conditioner’s circuit breaker is tripping, the first thing you should check is the filter and install a new AC filter if needed. To do this, simply locate the filter (it’s usually behind a grate on the front of the unit), remove it, and put in a new one. Once you’ve done this, turn the AC back on and see if the problem has been resolved. If the circuit breaker still trips, you may have a bigger issue that will require a professional to take a look at.

To avoid this problem, it is important to regularly clean or replace the air filter. By doing so, you can help keep your air conditioner running smoothly and prevent unnecessary circuit breakages.

Dirty Condenser Coils Tripping the Circuit Breaker

One of the most common reasons for an air conditioner circuit breaker to trip is dirty condenser coils. As the coils become clogged with dirt and dust, they become less effective at transferring heat. This causes the coils to overheat, which eventually trips the breaker. In addition, dirt and debris can also block airflow through the coils, causing the compressor to overheat.

If you notice that your air conditioner’s circuit breaker is tripping more frequently, it’s a good idea to have the coils cleaned by a professional. The condenser coils are often cleaned as part of a professional  maintenance tune-up for your air conditioning  unit, so make sure to schedule these each year to prevent circuit breaker problems caused by the condensing coil in the outside AC unit. With regular maintenance, you can help keep your air conditioner running efficiently and avoid costly repairs down the road.

Fan Problems in the Outdoor Unit

A broken coil fan in the outdoor unit can cause the air conditioner circuit breaker to trip for a few reasons. First, the fan is responsible for circulating air over the coils. Without the fan, the coils can’t do their job properly, and the air conditioner will overheat. Second, a broken fan can cause the coils to freeze up, which will also cause the air conditioner to overheat. Finally, a broken fan can cause the compressor to overheat, which is another reason why the air conditioner will trip the circuit breaker.

Sometimes, the fan blades may be causing the issue. Check the blades to make sure they are not damaged or obstructed. If there is debris blocking the condenser fan, turn off the power source to the air conditioner first, then carefully remove the material.

If the fan blades are damaged, or the problem seems to be due to the fan motor or other component, it’s time to call an AC tech for repairs. A broken coil fan in the outdoor unit is a serious problem that can cause the air conditioner to trip the circuit breaker. If you suspect that your fan is broken, it’s important to call a qualified technician for help.

Air Conditioner Tripping Due to Compressor Failure

Another one of the of the most common reasons why an air conditioner trips the circuit is because of a faulty compressor. The compressor is responsible for circulating refrigerant throughout the AC unit, and if it isn’t working properly, it can cause the unit to overheat. In some cases, the compressor may even start to leak refrigerant, which can be dangerous. If you notice that your air conditioner is tripping the circuit more frequently or if it’s starting to make strange noises, it’s important to have a professional take a look at it. Otherwise, you could end up damaging your AC unit beyond repair.

If you have an old AC unit, it may not be able to handle the increased load and will trip the circuit. In older models, the contactor closes with a spring-loaded plunger. The dust and dirt can cause the contact points to become corroded over time, which makes it harder for the contactor to close. This can cause arcing and eventually burning out the contactor. A failed or damaged capacitor will need to be replaced in order to get your air conditioner unit working properly again. Replacing a worn-out or damaged contactor is an inexpensive repair that can prolong the life of your air conditioner unit.

It may be necessary to install a hard start kit for your air conditioning compressor. A hard start kit helps to amperage the low voltage so the compressor can start with less strain. The capacitor provides a boost of energy so that the compressor can overcome any resistance and get started.

Bad Circuit Breaker or Loose Wiring to the Air Conditioning System

One of the most common reasons an air conditioner trips is because of a bad breaker. The breaker is what controls the flow of electricity to the air conditioner, and if it is not working properly, it can cause the air conditioner to trip. A bad breaker can be caused by a variety of things, including a loose wire or a problem with the breaker itself.

If you think your air conditioner has tripped because of a bad breaker, the first thing you should do is check the breaker to see if it is loose or damaged. If the breaker is loose, you will need to tighten it. If the breaker is damaged, you will need to replace it. You can usually find replacement breakers at your local hardware store.

If the wires are not properly connected, they can overheat and cause the circuit to trip. In some cases, the wires may also short-circuit, causing an electrical fire. If you suspect that your air conditioner’s wiring is to blame for its circuit problems, it’s important to have a professional electrician take a look at it as soon as possible. Otherwise, you could be putting your home at risk of serious damage.

Why Does My Air Conditioner Breaker Keep Tripping? Here’s Your Fix!

By Author Michael Joseph

Posted on Last updated: July 24, 2022

Your AC breaker is a safety feature that automatically turns off the system whenever a power overload is detected. If your air conditioner breaker keeps tripping, it’s because the system is taking in more amps than it’s rated for, which could happen for several reasons.

This happens to prevent damage to your equipment from overloaded circuits. So make sure that you don’t ignore the issue if it’s one that you’re having.

Most importantly, don’t continue to reset your AC breaker . Your main goal should be figuring out what the problem is so that you can solve it or hire a technician. We put together this article to help you do that, so keep reading to learn more.

Start with these steps

It bears repeating: You don’t want to just continue flipping back the breaker switch if it keeps tripping. Instead, follow these steps to start isolating the issue so that you can solve it safely:

  • Turn off your air conditioner at the thermostat.
  • Flip the AC circuit breaker switch into the “ON” position.
  • Wait for about 15 minutes with the air conditioner off.
  • Turn the air conditioner to the “COOL” setting.

Here’s what might happen next

After you complete the four steps shown above, there are three different things that might happen. We’ll cover each of those below.

1. It operates normally without tripping the breaker

If this happens, great! It’s a sign that your air conditioner is back to working normally. It means that your issue was likely tied to a momentary power surge or some other chance occurrence that won’t happen again.

These types of issues are generally not something you need to look further into unless they happen consistently. It’s often caused by a problem that’s external to your household.

2. It works for a while and then trips the breaker again

This could also happen, which can be frustrating. But the good news is that you may be able to solve the problem yourself. You can try replacing your AC air filter to see if that works.

Your air conditioner relies on a clean air filter to get the airflow that it needs to function properly. When the filter is dirty, the system has to work harder, and that can lead to overheating that trips the breaker.

Replacing your filter is super straightforward. You can refer to your owner’s manual to get step-by-step instructions that are specific to your system.

3. The breaker trips immediately

It’s also possible that the breaker will trip right away after you turn your AC back on. Unfortunately, this isn’t something that you’re likely going to be able to fix on your own. Instead, it’s time to call out an AC repair company to come and take a look at your unit.

You can also keep reading to learn more about the mechanical reasons why this keeps happening.

Here’s why your air conditioner breaker keeps tripping (from best-case to worst-case scenario)

The circuit breaker is faulty.

This is the best-case scenario because it means that you need to fix the breaker, not your AC unit. It means that your issue will probably be less expensive to solve.

There are a few reasons why this could happen. One is that you may have a circuit breaker box that doesn’t give your home enough power. For example, a 4.5-ton air conditioner typically needs a 35A breaker to work correctly.

It may also be as simple as a loose wire. These can happen due to natural contractions and expansions that occur when the temperature changes over time.

Here are some of the top signs that you’ve got a bad breaker:

  • There’s a burning smell near the breaker box. This can happen when wires and their insulation get overheated.
  • Your breakers are hot to the touch. This is self-explanatory. The same heat that leads to your wires burning can also cause the breakers themselves to get warm.
  • You can see visible damage on the circuit breaker.

The solution to a bad breaker is to replace it with a new one . You can confirm that this is necessary by seeing if a breaker is loose when you manipulate it.

The good news is that these are pretty inexpensive and not the most challenging thing to replace. But if you’re not comfortable with electrical work, then an electrician should be able to handle it for you at a reasonable price.

You have dirty condenser coils

It’s also possible that your air conditioner circuit breaker keeps tripping because you’ve got dirty condenser coils. This part’s job is to release heat from the inside of your home outside. It’s typically on your outer unit, which means it’s constantly exposed to the outside elements (wind, snow, etc.).

Condenser coils may get covered with various types of grime and debris periodically. When this happens, they aren’t able to release the heat that they need to. This causes your AC to work harder and can lead to overheating that trips the safety breaker.

You should be able to see this visibly, as most modern units discharge warm air out of the top.

Fixing this problem may be as simple as cleaning the condenser coils . You can open up your outdoor system and look for any dirt. When you see some, spray it with a cleaner and wipe it with a rag.

Luckily, you don’t need a complicated cleaning solution for this task. You can just mix together some warm water with your favorite cleaning product, and that should be enough.

Your fan motor is malfunctioning

The overheating problem that you’re experiencing may also be tied to your air conditioner’s fan motor.

This problem is similar to what can happen with your condenser coils. The same outside elements could reduce the efficiency of your fan, which causes the AC unit to have to work harder.

That creates a situation in which your air conditioner is drawing more electricity than it would normally need to compensate for the lack of efficiency. If this happens consistently, the capacitor can overload. And your air conditioner will trip your breaker as a result.

You can check for this issue by looking to see if your outdoor fan is spinning . If it is, then your problem may lie elsewhere. But if it’s not, you might have a broken fan motor that needs to be replaced. It will cost about $250 to $700 to replace on average.

That being said, make sure to look into the various reasons why a fan may not be spinning . Because it can be indicative of several different problems.

Your evaporator coils have frozen

It’s also possible that your evaporator coils have frozen, and that’s causing your AC circuit breaker to trip continuously. This can happen when too many debris accumulates in your system and airflow is reduced.

This is a pretty straightforward issue to spot. Simply take a look at your evaporator coils and see if there’s any ice on them. You may also want to check for puddles of water nearby in case they’ve recently thawed.

The solution is to give your evaporator coils 24 hours to thaw out . While that’s going on, you can clean the coils to make sure this doesn’t happen again.

You may also want to give your entire air conditioner a thorough cleaning and swap out the air filter. The cleaner your system is, the more airflow that it gets. And that will decrease your chances of experiencing frozen coils again the next time you use your air conditioner.

You’ve got low refrigerant levels

Air conditioners use refrigerant to cool down the air that they process. This liquid is designed to be a closed loop that doesn’t need topping up under normal circumstances.

However, sometimes you can get punctures in your refrigerant lines, which lead to lower refrigerant levels over time. This will cause your system to pull in too much power and may lead to tripped breakers.

The only solution to this problem is to call an HVAC professional . Refrigerant is a toxic liquid that isn’t safe to deal with unless you know the proper way to do so. To avoid putting yourself or your family at risk, it’s best to let a professional take over from here.

The compressor isn’t starting

Finally, the problems you’ve been experiencing could also stem from the compressor itself. It may have trouble starting, which could cause it to draw in too much power and trip the breaker immediately.

Normal AC units should turn on within about a second of the time that you flip the switch. If your air conditioner takes longer than that to get going, it’s a big sign that you’ve got a compressor issue.

The unfortunate news is that compressor repairs and replacement cost about $1,250 on average . That means it may make more sense to just replace your system with a new one at this point—especially if you’ve had the current AC for a long time already.

Either way, your next step is to call an HVAC professional so they can diagnose the problem and advise you on your options.

6 REASONS YOUR AIR CONDITIONER KEEPS TRIPPING THE CIRCUIT BREAKER

Circuit breaker panel with cover open

So, you've determined that your AC is tripping the breaker, but you're clueless as to why.

Well, an air conditioner usually trips the breaker because it's pulling in more amps than the breaker is rated for. That is, if you have a 20-amp breaker and the AC pulls 30 amps, the breaker trips.

That's why breakers trip: to protect you from over currents that can damage equipment and cause fires (yikes).

So DON'T keep resetting the breaker and letting it trip. Constant tripping can harm equipment and cause a fire. Find the cause of the problem first.

Common causes of an air conditioner tripping the breaker include:

  • Dirty air filter
  • Dirty outside unit
  • Issue with the circuit breaker
  • Motor has shorted
  • Compressor has trouble starting
  • Compressor is grounded

You can fix the first problem yourself, but everything else requires an AC repair technician.

Read on to learn why these problems cause an AC to trip the breaker.

Or you can schedule an AC repair with us right away if you live in the metro Atlanta, GA area .

Now, on to the reasons your AC keeps tripping the circuit breaker

  • Dirty air filter Imagine forcing a pillow over your face. Hard to breathe right? That's what a dirty filter does to your AC blower; the blower has to work longer and harder to circulate air through the filter. This causes the blower to draw more electricity and trip the breaker. Solution : Change the air filter.
  • Dirty outside unit Your AC system has an inside unit and an outside unit. The inside unit absorbs heat from your air using refrigerant. That refrigerant flows to the outside unit to disperse the heat. However, the outside unit can't disperse heat well if it's super dirty because dirt is an insulator. So the AC runs and runs trying to disperse that heat outside until-click-the breaker trips due to drawing too much current. Solution: Get an AC tech to properly clean the outside unit. You may be thinking, "Why can't I clean it myself?" Well, you lack the cleaning equipment and cleaning chemicals to clean the condenser coil professionally (and buying the wrong type of equipment can do more harm than good to the condenser). Plus, cleaning it improperly could damage/flatten the fins wrapped around the coil. This blocks airflow over the coil and is just as bad as having the coil matted with dirt.
  • Issues with the circuit breaker The issue may not be with the AC itself but rather with the breaker. Wires connected to the breaker may be loose or the breaker itself may be bad and needs replacing. This is a relatively inexpensive fix. Solution: Have a tech tighten connections to the AC's breaker or replace the breaker.
  • Motor has shorted Electric motors in your AC can run for hours and hours and can take quite a bit of abuse. But if a motor runs hot for too long, the wire insulation can break down, leading to an electrical "short." A "short" is where electricity bypasses its normal path, (so it's taking a "shortcut"). This shortcut allows more electricity to flow than the wires can handle, causing the wires to overheat, melt and cause a fire. Of course, before the fire happens, the circuit breaker trips. Solution: Call an AC repair technician to find the source of the short.
  • Compressor has trouble starting The heart of your AC system is the compressor. It pulls tons of electricity when it starts up. Unfortunately, as the compressor ages, it has trouble starting (called hard starting) and pulls even more electricity, causing the breaker to trip as a result. Solution: Have an AC technician install a "hard start kit" which is a capacitor that gives the compressor motor an extra electrical "jolt" to get it moving. However, the compressor may be old or damaged and need to be replaced instead.
  • Compressor is grounded A "grounded compressor" or "compressor short to ground" means that an electrical winding inside the compressor has broken and hit the side of the compressor. This causes a direct short to ground, igniting the oil and causing a burnout. And, of course, the circuit breaker trips due to the sudden current surge. Solution: This is the worst-case scenario. An AC tech will have to replace the compressor and clean the refrigerant lines. If your compressor is out of warranty (or your warranty never covered it), you might as well replace the entire outside unit. Cheaper that way. (Compressors are pricy.)

AC Breaker Keeps Tripping? Here’s What You Need to Know for a Quick Fix

We know this can be a bothersome problem, but we’re here to help you get it sorted out quickly and easily. An AC breaker that trips often is usually caused by an issue with your circuit wiring or by a malfunctioning appliance.

If your AC circuit breaker keeps tripping, there are several potential reasons.

Identifying the source of the issue before attempting any repairs is essential. Once you’ve identified the source of the problem, we’ll explain how to take care of it in just a few simple steps. If your AC breaker keeps tripping and you’re looking for a quick and easy fix, this article is for you!

What Is an AC Breaker?

An AC Breaker is a crucial safety feature in your home’s electrical systems that helps protect against overloads and short circuits. It works by breaking the circuit and cutting off electricity when it senses an overloaded or short-circuited wire.

You can find these devices in your main electrical panel, as well as individual outlets and switch boxes throughout your home – making sure that you and your family are always safe from harm.

The AC breaker consists of two parts: a circuit breaker switch and a trip indicator. The circuit breaker switch is responsible for cutting off power when it detects an overload or short circuit – this prevents further damage to your wiring and appliances.

The trip indicator shows whether the breaker has been tripped, allowing you to reset it if necessary.

Why Do AC Breakers Trip?

If your AC keeps tripping the breaker, the most common causes are either too much current being drawn from one circuit or a short circuit caused by faulty wiring or a damaged appliance.

If any of these conditions are present, it can cause the breaker to trip and shut off the power to that area of your home.

Other potential causes include a failed motor or compressor in your air conditioner or even dust accumulation on the breakers themselves.

What To Do When Your AC Breaker Trips

Is your AC tripping the breaker? It can be an annoying and inconvenient issue to deal with. But don’t panic – there are a few simple steps you can take to try and fix the problem.

Check your air conditioner’s filter. A clogged filter can cause the breaker to trip by overloading the circuit. Replace or clean it if needed.

Look for any signs of damage on the wiring leading up to the AC unit. If the wiring looks frayed or damaged in any way, call a licensed electrician for help as soon as possible.

If none of these solutions work, it might be time to upgrade your electrical panel or have an electrician install a higher-capacity breaker specifically designed for your air conditioning system. By taking these steps now, you can avoid costly repair bills down the road and get back to feeling comfortable in no time!

Common Causes of AC Breakers Tripping

There are many possible reasons why your AC unit keeps tripping the breaker. Below, we’ll take a look at some of the most common.

A Dirty Air Filter

One of the most common causes of an AC breaker tripping is a dirty air filter. When an air filter becomes clogged with debris, it can cause your system to work harder than it needs to and eventually trip the breaker.

You’ll want to ensure you regularly check and replace your air filters to keep them clean and functioning properly.

Dirty Condenser Coils

Another potential culprit for a tripped AC breaker is dirty condenser coils. These coils are responsible for releasing heat from the system, so if they become covered in dirt or other debris, they won’t function as efficiently and could potentially cause your breaker to trip.

Make sure you routinely inspect and clean your condenser coils for optimal performance. If your AC trips the breaker after 5 minutes of working, this is a possible cause.

Broken Coil Fan

A broken coil fan could also be causing your AC’s breaker to trip. The fan helps circulate cool air throughout the room, but when it stops working properly, this disruption can put a strain on the system and cause it to trip the breaker as a safety measure.

If you suspect that your coil fan may be malfunctioning, contact an HVAC technician right away so they can diagnose the issue and repair any damages quickly.

Problematic Compressor Start-up

One of the more common causes of an AC breaker tripping is a problematic compressor start-up. If your compressor is having trouble starting up, it can draw too much current and cause the breaker to trip. This problem is usually caused by faulty wiring or parts, such as a capacitor or motor winding.

Loose Wiring or Faulty Parts

Loose wiring or faulty parts are also frequent culprits behind AC breakers tripping. Loose connections can create dangerous arcs that will cause the breaker to trip.

Additionally, if some internal part in your AC unit has become damaged and isn’t working properly, it could also lead to an overload that trips the breaker.

Too Little Refrigerant

Another common reason for AC breakers tripping is too little refrigerant in the system. This can happen when there’s a leak in the system somewhere, which causes the refrigerant levels to drop below the required amount for your AC unit to work properly.

When this happens, your unit will have difficulty cooling down and not be able to handle large loads efficiently—causing it to trip its own breaker as a safety measure.

The Compressor Is Grounded

If your AC’s compressor is grounded, then it could be the cause of your breaker tripping. This can happen if a wire becomes loose or disconnected or if the wiring around the compressor has been damaged due to corrosion or wear and tear.

To check for this issue, you should inspect the wiring and connections around the compressor. If all looks okay, you’ll need to call in a professional to take a closer look.

The Evaporator Coil Is Frozen

Another common cause of an AC breaker tripping is a frozen evaporator coil . This occurs when air isn’t flowing properly through the unit, and as such, causes an overload on the system, which trips the breaker switch.

To fix this issue, you’ll need to clear any blockages from your AC vents so that airflow can be restored. You may also need to replace any broken parts inside your unit for optimal performance and safety.

The Circuit Breaker Is Faulty

If your AC circuit breaker keeps tripping, it’s possible that your circuit breaker itself is faulty and needs replacing in order for it to operate correctly again. A qualified electrician will be able to diagnose whether this is an issue by testing the circuit breaker for any signs of wear or damage.

A qualified technician can accurately diagnose why your AC circuit breaker keeps tripping.

If you do find yourself needing a new one, ensure to get one with an appropriate amperage rating that matches up with your home’s electrical system requirements!

While the steps listed above are excellent ways to identify why your AC breaker keeps tripping, we wouldn’t recommend working with electricity without some form of training. The problems are often relatively minor, but the risks involved when working with electricity simply aren’t worth it to save a few bucks.

The bottom line is that if your AC breaker keeps tripping, the best thing to do is to call a qualified AC technician for help. An experienced technician can diagnose why your AC breaker keeps tripping and then take steps to ensure it doesn’t happen again.

While it may seem like a hassle, having your AC breaker checked out by an expert can help you avoid costly repairs down the road. Safety should always come first when dealing with electricity – so don’t take any chances!

If you have an AC unit, you’ve probably wondered how long it will last. And why wouldn’t you? You’ve spent a lot of money on your unit.

When it comes to keeping your home comfortable, the choice between a heat pump and central air conditioning can feel like a crossroads. Each…

How to Choose Best HVAC Systems

Why Is My Air Conditioner Tripping the Circuit Breaker?

why breaker trips on ac

Reasons for the AC to trip the circuit breaker range from the obvious “human error” issues with easy fixes to more complex matters for handy homeowners or licensed technicians to repair.

It’s a hot day and your house is uncomfortably warm. The thermostat is set to “cool” and the selected temperature is much lower than the displayed room temperature, but your AC unit is not working. A check of the circuit panel reveals that the breaker marked, “A/C” is tripped; it’s in the “off” position. Flipping it back to the “on” position has not solved the problem. Maybe the AC ran for a while and stopped again, or maybe the breaker tripped again immediately and won’t reset.

You might call a competent repair service and leave it to them to diagnose and fix the problem, but if you are a little bit handy – or even very handy – you might want to see if you can take care of it yourself before calling in the pros. Here are some things that can cause your AC circuit breaker to trip, and some things you might be able to do about it.

Non-Electrical Causes of the AC Tripping Circuit Breaker

Check these before calling for service.

1. Your Outside AC Unit Has a Cover On It

At any big box store, your local hardware, or online, covers for the outside component of your AC system – the condenser – are available from as little as $10 to over $100 , depending on the materials used to make them. Some people like to put a cover on their condenser even though they usually don’t really need it. But what happens if you forget to remove it before starting up your AC in the Spring? The unit will quickly overheat and the circuit breaker will trip. Simply remove the cover and allow the unit to cool down before trying it again.

2. A Very Dirty Furnace Filter

Here’s another one that just requires a gentle reminder.

why breaker trips on ac

Your central air conditioning system is part of the complete heating and cooling (HVAC) system in your home. It uses the same air ducts to circulate air throughout your house, and the same air filter through which all this cool (or warm) air flows. That means it is used much of the time, has a lot of air pass through it, and collects a lot of dust, dirt and pet hair (human hair, too).

Dirty Air Filter

If the filter is very dirty, it can cause the AC system to work so hard that it will trip the circuit breaker. Change your air filter at least every 3 months, and if you find it to be quite dirty at that time, you might want to check it monthly just to make sure it’s not too dirty.

3. A Dirty Condenser Coil

This is located in the outside AC unit, the cabinet that is usually in the back of your home or on a side where it is not easily seen. Inside this cabinet – around the sides – is the condenser coil. It looks something like a vehicle radiator, with many shiny aluminum “fins” and tiny openings for air to travel through. When the AC is running, air is drawn in through the sides of the cabinet, through the condenser, then out through the top by a fan. Dust, dirt, leaves, seeds and other outdoor debris can get trapped in the condenser coil and cause an “overload” when the system tries to start, tripping the circuit breaker.

dirty evaporative coil

To solve this problem, first make sure to disconnect the power to the outside AC unit. There is usually a disconnect plug very close to this unit which should be pulled out. It is also a good idea to turn the AC off inside the house. Remove the fan and grill from the top of the cabinet with the screws holding it in place and set the fan off to the side, being careful to not damage its connecting wires.

Rinse the condenser coil thoroughly with water, either with a nozzle on a spray setting, or just by squirting it from the hose with your finger. Do not use a pressure washer. Too much pressure can damage the delicate fins and keep the unit from circulating air efficiently. It is best to rinse from the inside out, so as to not push the offending debris deeper into the coil.

We’ve recommended the top tips and the Best Coil Cleaners in this Guide .

4. Too Little or Too Much Refrigerant

This isn’t one you can check, but it’s a possibility to discuss with an HVAC pro.

Every AC system uses a special liquid refrigerant which circulates through its components to make it work efficiently. The system is sealed, so it usually doesn’t require any additional refrigerant for life. If your AC has developed a leak, it will lose refrigerant, cause it to malfunction, and possibly trip the circuit breaker.

Normally, when a competent technician has fixed a leaking problem, everything should work as it is intended to.

However, if the technician somehow “overcharged” your system by putting too much refrigerant in, that can also result in a tripped AC circuit breaker. Always be sure to hire a well-respected and competent service technician if you need professional help with your AC.

Electrical Problems

Some of these are DIY opportunities if you are familiar with electrical systems and testing them.

1. Burned Out Condenser Fan Motor

This is the fan motor located at the top of the outside cabinet. If this motor burns out, it can definitely cause the AC circuit breaker to trip. One simple test that you might try to confirm that this is the problem is to gently spin the fan blade with a stick or long screwdriver. The fan blades are easily seen through the grill on top of the cabinet. If the fan turns very sluggishly or barely turns at all, the motor is most likely burned out.

Another, but more involved way to test the fan motor is to trace the wires from the fan motor to the electrical component panel. This panel will be located on the same side of the cabinet that the wires come in from your house. First, make sure to pull the disconnect plug near the outside unit. Remove the side panel and find the wires from the fan motor. Identify them by their colors. Remove them from the terminals and make sure they are not touching any metal or each other.

Now turn on the AC. If it doesn’t trip the breaker with the wires removed, the problem is with the fan motor. To confirm this, turn off the breaker again, replace the fan motor wires in the panel and turn the breaker back on. A burned out fan motor will cause the circuit breaker to trip again and it won’t reset. Contact a competent technician to replace it if you do not feel that you can do the job yourself.

2. Bad Wiring/Wire Shorted to Ground

This problem would most likely be in the outside cabinet. After first pulling the disconnect plug, a careful inspection of all wiring is what is needed to find the trouble. Check all wiring between the disconnect and the cabinet. Look for damaged areas – perhaps where wires run into the cabinet, though they are often in a conduit.

Remove the side panel where the wiring enters the cabinet; all the electrical stuff is there. Look for mouse nests, chewed or broken wires, especially those that lie against the metal cabinet. If a bad wire is found, cut and reconnect it with a butt connector and crimp pliers.

Another place to check is inside the box on the side of the compressor. The compressor is the “can-looking” part that is located on the bottom of the cabinet, and must be accessed by removing the fan and top grill. There are 3 wires inside the box on the side of the compressor. Check these wires for frayed areas, especially if they are lying against the side of the box.

A problem with one or more of these 3 wires can be fixed with a QwikLug™ repair kit that can be purchased at most big box stores or anywhere that sells AC supplies.

3. The Compressor Is Drawing Too Much Power On Start Up

Do the lights in your house dim whenever the AC starts. This could be the reason.

The compressor does a lot of work, and especially after several years, can begin to draw more electrical power due to wear. This is not too unusual and can often be at least temporarily fixed by installing a “hard start” kit . This can reduce the amperage draw on start up by up to 50%. If you’re handy with electrical components, you may be able to do this yourself. If not, be sure to hire a competent service technician.

4. The Compressor Is Shorted Out/Shorted to Ground

If your AC breaker keeps tripping, a shorted out compressor is another likely cause. If it is, installing a new compressor is the solution, but it is usually best to replace the entire condenser, the whole outside component of your central air system. Bad compressors usually only happen in older air conditioners, and it’s more cost effective to start with a completely new condenser unit than to try to put an expensive new compressor in an old system. According to our AC Repair Guide , compressor replacement cost is $1,250 to $2,500 based on the size and model of the condenser unit. That money is probably best spent on a new system if your current unit is no longer under warranty.

Pro Tip: Make sure your warranty stays in effect by having your AC serviced every year – and keeping the records!

Like roofing companies, car manufacturers and others, HVAC equipment companies are notorious for denying warranty claims. Most warranties state that the homeowner must have the system serviced by a pro every year or the warranty will be voided. So, look for an HVAC company with a good reputation and affordable service plans, and sign up for one. With a service plan, you’ll get discounts on the maintenance and possibly on repairs too. There’s more information in our HVAC Warranty Guid e, the most comprehensive of its type.

To test to see if your compressor is bad, first pull the power disconnect near the outside cabinet. Remove the grill and fan from the top by taking out the screws that hold it in place and carefully set it to one side. On the bottom of the cabinet, you will see the compressor, while the aluminum condenser coils will be on the sides.

Near the bottom of the compressor will be a box where the wires come in. Remove the cover to this box, and you will find 3 wires. There are two ways to test for a bad compressor; with or without a multi-meter.

With a meter: Set the meter to “continuity” or ohms (Ω). Pull one wire off at a time and check the pin (not the wire) for continuity to the compressor case. They should all test “open” or OL. If any of the wires test otherwise, that pin is shorted to the casing, which is ground. This means the compressor is bad.

Without a meter: With all 3 wires removed and not touching each other or the case, turn on the circuit breaker in the house and reconnect the disconnect plug by the outside unit. At the thermostat, make sure that the AC is on and at a temperature low enough to call for cooling. If the circuit breaker does not trip, the problem is probably a grounded compressor.

To confirm this, turn off the AC again, pull the power disconnect plug and replace the 3 wires on the compressor. Replace the power disconnect plug and turn on the AC again. If it immediately trips the circuit breaker and it won’t reset, it is definitely a grounded compressor.

5. A Defective Contactor

The contactor is another electrical part in the outside AC unit. This can go bad, but it is quite unusual for it to happen. It must be tested with the power on, and is best done by a competent service technician. Does the unit sometimes buzz too? This is a clue that it is the contactor!

6. A Weak Circuit Breaker

If your AC breaker keeps tripping, it could be worn out. Sometimes – over time – circuit breakers can become “weak” and will trip, especially when a load is first placed on them. In one sense, this is a simple problem because it only requires replacing the breaker. However, it should not be considered lightly, because it requires the opening of the main power panel in the house and working with “live” power inside the panel.

If you have checked everything else and are still having trouble with the AC circuit breaker tripping, it’s best to contact a service technician to replace the breaker unless you are fully acquainted with working inside power panels.

When it comes to an AC circuit breaker tripping, one thing is sure: there is a definite reason for it to be happening. Just remember, central AC systems operate on 240 volts of electricity, so if you suspect any of the problems that appear to be electrical, be very careful unless you know what precautions to take. If not, be sure to contact a professional in your area who will be able to help you.

Why Does Air Conditioner Breaker Keep Tripping?

One of the most common reasons for an air conditioner breaker to trip is a dirty filter. When the filter gets clogged with dust and dirt, it puts strain on the motor which can cause it to overheat and trip the breaker. If this is the case, simply replacing the filter should fix the problem.

Another possibility is that there’s an issue with one of the electrical components in your AC unit. This could include a faulty capacitor or contactor. If you suspect there may be an electrical issue, it’s best to call in a professional for help.

Trying to fix it yourself could be dangerous if you’re not experienced in dealing with electrical issues.

Why Does Air Conditioner Breaker Keep Tripping

How do I stop my AC from tripping the breaker?

If your air conditioner keeps tripping the breaker, there are a few things you can check yourself before calling a professional.

First, check to see if the breaker is properly sized for your AC unit. If it is too small, it will trip more easily. Second, check for any loose wires or other electrical problems that could be causing the breaker to trip.

Finally, make sure the AC unit is properly ventilated. If it is not, it can overheat and trip the breaker.

Why is my AC breaker popping?

Assuming you have a central air conditioning unit, there are several reasons why your AC breaker might be popping.

One reason might be that your AC unit is overloaded. This can happen if you have too many appliances plugged into the same circuit as your AC unit. To fix this, you can either unplug some of the appliances, or plug your AC unit into a different circuit.

Another reason might be that your AC unit is faulty. This could be due to a number of different issues, including a short circuit, a loose wire, or a problem with the compressor. If you think your AC unit is faulty, you should call a qualified technician to come and take a look.

Finally, if your AC unit is old, it may simply be that the breaker is worn out and needs to be replaced. This is a relatively easy fix – just replace the breaker with a new one. If your AC breaker keeps popping, it’s important to figure out the cause so that you can fix it. Otherwise, you run the risk of damaging your AC unit or causing a fire.

How do you know if your AC breaker is bad?

If your AC unit isn’t working, one possible reason is that the breaker is tripped. To reset the breaker, simply flip it to the “off” position and then back to “on.” If the breaker trips again, this is an indication that there is a problem with your AC unit and you should call a technician for further diagnosis.

Ac Trips Breaker Immediately

If your air conditioner trips your breaker immediately, there are a few things that could be causing the problem. The most likely culprit is a short circuit in the AC unit itself. This can be caused by a number of things, including a loose wire or a faulty component. If you suspect a short circuit, you should call an AC repair technician to come take a look. Another possibility is that your AC is simply overloaded. This can happen if it’s working harder than usual to cool your home, or if it’s been turned on after being off for a while. In this case, you’ll just need to give the unit some time to rest before turning it back on. If the problem persists, though, it’s worth calling an AC repair technician to take a look and see if there’s anything else going on.

Ac trips breaker after 5 minutes

If your air conditioner trips your breaker after just five minutes, there could be a few different issues at play. First, check to see if your unit is overloading the circuit. If your AC is the only thing on the circuit, and it’s tripping the breaker, then it’s likely that your unit is too powerful for the circuit it’s on. You’ll need to have an electrician rewire the circuit to a higher capacity, or move the AC to a different circuit. Another possibility is that there is a short circuit somewhere in the AC unit. This could be caused by a faulty wire or component. You’ll need to have an AC technician take a look at your unit to diagnose and repair the problem. Finally, it’s possible that the breaker itself is faulty. This is most likely if the breaker trips as soon as the AC is turned on, or if it trips regardless of what else is on the circuit. If you suspect the breaker is the problem, you’ll need to have an electrician replace it.

Ac breaker tripped and won’t reset

If your air conditioner’s circuit breaker has tripped and won’t reset, there are a few possible causes. The most common cause is a power surge or spike, which can overload the circuit and cause the breaker to trip. Other causes can include a short circuit, or a problem with the air conditioner itself. If you suspect a power surge or spike is the cause, unplug the air conditioner and check the circuit breaker. If it is still tripped, you may need to reset the breaker or have an electrician look at the system. When the breaker trips again, there may be a problem with the air conditioner itself and you should call a repair technician.

How to reset ac circuit breaker?

If your air conditioner keeps shutting off, it may be time to reset the circuit breaker. Circuit breakers are designed to trip when they sense an overload of electricity. This protects your air conditioner from damaging itself with too much power. To reset the circuit breaker, find the breaker box and flip the switch to the “off” position. Wait a few minutes, then flip it back to the “on” position. If the breaker trips again, it’s time to call a professional to help you troubleshoot the problem.

Ac compressor tripping after few seconds

If your AC compressor is tripping after just a few seconds of operation, there could be several reasons behind it. One possible cause is an electrical issue, such as an overloaded circuit breaker or a short circuit. To address this, it is recommended to contact a qualified electrician who can inspect and resolve the problem.

Another potential cause could be dirty condenser coils, which can impede airflow and cause the compressor to overheat. To rectify this, ensure that the coils are clean and free from debris. You can either use a coil cleaner or seek assistance from a professional HVAC technician to spotless them.

Low refrigerant levels can also lead to the compressor tripping. If the refrigerant levels are too low, it may indicate a leak in the system. To address this issue, it is best to contact a professional HVAC technician who can locate and repair the leak and then recharge the refrigerant to the appropriate levels.

A faulty capacitor is another possible culprit. The capacitor provides the initial power boost required to start the compressor. If it is defective or failing, it can cause the compressor to trip. A qualified technician can test the capacitor and replace it if necessary.

Finally, the compressor motor may be experiencing excessive load or mechanical issues, resulting in frequent tripping. This could be due to a faulty motor or compressor itself.

To diagnose and repair this problem, it is advisable to consult a professional HVAC technician who has the expertise and equipment to handle such issues safely.

Ac compressor tripping after few minutes

If your air conditioner’s compressor is tripping after only a few minutes, there are a few possible causes. The most likely culprit is a problem with the compressor itself. It could be overloading, or it could be faulty. If the compressor is the problem, you’ll need to have it repaired or replaced. Another possibility is that the problem is with the air conditioner’s electrical system. If the compressor is tripping the circuit breaker, there may be a problem with the wiring. It’s also possible that the air conditioner is drawing too much power, and the circuit breaker is tripping to prevent a fire. If you suspect that the electrical system is the problem, you should have it inspected by a qualified technician. Finally, it’s possible that the problem is with the air conditioner’s refrigerant levels.

If the compressor is tripping because the refrigerant levels are too low, you’ll need to have the air conditioner serviced to add more refrigerant. If your air conditioner’s compressor is tripping after only a few minutes, there are a few possible causes. The most likely culprit is a problem with the compressor itself. It could be overloading, or it could be faulty. If the compressor is the problem, you’ll need to have it repaired or replaced. Another possibility is that the problem is with the air conditioner’s electrical system.

Circuit breaker for air conditioner

If your air conditioner keeps tripping your circuit breaker, there are a few possible explanations. The most common cause is a problem with the air conditioner itself. If your air conditioner is old, it may be time for a replacement. Another possibility is that the air conditioner is overloaded and needs a bigger circuit breaker. If you have a newer air conditioner, the problem may be with your electrical wiring. If your circuit breaker is constantly tripping, you should have an electrician check your wiring to see if it is up to code. When your air conditioner is tripping your circuit breaker, don’t ignore the problem. It could be a simple fix, or it could be a sign of a more serious problem. Either way, it’s best to have a professional take a look to be safe.

Can a bad ac capacitor cause the breaker to trip?

If your air conditioner’s capacitor is bad, it can cause the breaker to trip. The capacitor is responsible for providing the electrical current that helps start up the compressor. If the capacitor is damaged, it can’t provide the necessary current, which can cause the breaker to trip.

Refrigeration compressor tripping breaker

If your refrigerator’s compressor is tripping your breaker, there are a few possible causes. The most common cause is a faulty compressor start capacitor. A start capacitor gives the compressor a boost of energy to start, and if it’s failing, the compressor can’t start properly. Another possibility is that the compressor itself is faulty. If the compressor is drawing too much power, it can trip the breaker. This is usually caused by a problem with the compressor’s internals, and will require a replacement. Finally, it’s possible that the breaker is simply too small for the refrigerator. If the fridge is new or has recently been upgraded, the breaker may not be able to handle the increased load. In this case, you’ll need to upgrade the breaker to a higher capacity.

Air conditioner circuit breaker outside

If your home doesn’t have central air conditioning, you may have an air conditioner circuit breaker outside. This circuit breaker controls the power to your air conditioner unit. If the circuit breaker trips, it will cut off power to your air conditioner unit. This can be a problem if the weather is hot and you need to cool down your home. To reset the circuit breaker, you’ll need to locate it first. It should be near your air conditioner unit. Once you’ve found it, flip the switch to the “off” position and then back to the “on” position. This should reset the circuit breaker and restore power to your air conditioner unit. If the circuit breaker trips again, it’s possible that there is a problem with your air conditioner unit. You may need to call a technician to come and take a look at it. In the meantime, you can try to cool your home down with fans.

Why Does My Air Conditioner Circuit Breaker Keep Tripping?

The most common reason for an AC breaker to trip is because it is overloaded. This means that there is too much current flowing through the breaker, and it trips to protect the circuit. Other reasons for an AC breaker to trip include a short circuit, a ground fault, or a faulty breaker.

why breaker trips on ac

Why Is Your AC Tripping Your Circuit Breaker? 

If you notice that your AC is tripping the breaker, then it may be time to contact a professional. There are many reasons why this could be happening, and each of them requires different solutions. 

For example, if you notice your AC system is tripping the breaker when it gets too hot outside, then you might need an ac pro to come out and give your unit a tune-up. 

Sometimes air conditioners will cause circuit breaker trips because they are not getting enough electrical current from the AC circuit breaker, or there may be something wrong with the wiring in your house. 

Let’s take a look at the top five common causes for why your air conditioning system could be tripping your circuit breaker. Finding the issue and trusting a professional with your AC repair can keep your family cool and safe this Summer!

AC Acting Up?

Is your AC acting up? Don’t put up with warm air- our team is here to help!

1. A Dirty Air Filter 

If you notice that your AC is tripping the breaker when it gets too hot outside, a dirty air filter may be to blame.  Dirty filters can reduce airflow and cause AC units to overheat, resulting in a breaker trip. 

They also make it difficult for air conditioners to function efficiently at colder temperatures, so you might notice your AC is not cooling your home like it used to.

Air filters should be cleaned every few months depending on how often you use your air conditioning unit and where you live (it might need more cleaning if there are many allergens or plants in your area). 

Your best option is always going to be calling in an HVAC technician who knows precisely what they’re doing when dealing with electrical wiring like this. If somebody with proper HVAC training is not appropriately handled, there could be severe consequences for both property and personal safety.

2. Dirty Condenser Coils

When your condenser coils get dirty, they cannot disperse heat from inside the house to the outside unit .  This can cause the air conditioning system to lead to an electrical short, which can overheat. 

Even when it is running, the A/C unit requires more electrical current to push the heat out of your home, which leads to a short circuit. 

Dirty coils are usually caused by a buildup of dirt, dust, or plant life in your outdoor unit. Cleaning out these coils will help you avoid future ac problems like this!

To prevent dirty condenser coils, you want to make sure that your AC pro is coming out and doing regular tune-ups on the unit.  Tune-ups should be done at least once per year to prevent heat loss in your home during these hot summer months!

An AC pro will also know how often a coil needs to be cleaned or replaced. Some units don’t need cleaning until they are no longer working correctly, while others may only need an annual cleaning depending on their age and performance level. 

3. Broken Coil Fan

Air conditioning units use fans inside them called “coil” fans for cooling purposes, which are often powered by motors outside the house. This fan blows over the coils to release heat from your inside unit. 

If there is something wrong with these motors – whether they have been damaged through wear and tear over time or if they were cut out during construction work nearby-then this could result in increased energy usage and cause the coil fan to burn out sooner than expected.

If your air conditioner fan motor is tripping the breaker because it’s not getting enough power from your circuit, then a broken coil fan may be to blame.  Broken or missing parts of an ac unit can cause this issue that results in higher electricity usage and possible breakers trips. 

To fix this problem, you’ll need an HVAC pro who knows how to replace or repair the coils on air conditioning!

4. The Compressor Is “Hard Starting”

The compressor is an essential part of your AC unit, and as the compressor ages, it may experience problems starting up. If the circuit breaker keeps breaking, you might need to have an HVAC technician check the flow of electricity between the fan and your circuit. 

A running AC unit should switch on in about one second – so anything longer than that could be a sign that you have an issue with your compressor. 

If your compressor is “hard starting,” you will need to call a professional to diagnose the issue. The entire compressor may need to be replaced, plus the refrigerator lines will need to be cleaned to ensure no particulates are in the lines that can cause problems down the road. 

5. Loose Wiring & Aging A/C Parts

Your A/C unit is a complex maze of wires that keep the entire system working. Over time, these wires may become loose and lose their connection, and this can cause your circuit breaker to trip from time to time.  

An AC pro will fix this by re-wiring your circuit and may also need to replace the metal plate that contains all of your wires.  The ac pro can provide a new one, or you can purchase one separately on Amazon at an affordable price!

Don’t Risk Your Investment by Running Your AC with a Tripped Breaker.

How much is your peace of mind worth to you? Think about it, if your AC breaker keeps tripping and shutting off because there’s an underlying issue with the system, not only are you dealing with a hothouse day in and day out, but when Summer comes around again – that’s a whole lot more money. 

The best thing you can do for yourself (and the environment) is to get a professional AC repair service as soon as possible to identify and fix any issues before they become chronic. 

You may be able to save yourself from suffering through another scorching summer this year by taking care of your air conditioner now!

Why Your AC Breaker Keeps Tripping

resetting tripped circuit breaker

From electrical issues to equipment malfunctions, several factors can cause an AC unit to keep tripping the breaker. Let’s explore some common causes and cover ways to diagnose and resolve this issue.

What Is an AC Breaker?

An AC breaker is a safety device that protects the electrical circuit that powers your air conditioning system. It’s typically located in your home’s electrical panel or breaker box. The AC breaker acts as a switch that can be turned off manually to interrupt the flow of electricity to the AC unit in case of electrical faults, overloads, or short circuits.

When a problem arises that could damage the electrical system or pose a safety hazard, the breaker automatically trips, cutting off power to the AC unit to prevent further damage or fire hazards.

Why Does My AC Breaker Keep Tripping?

Your AC can trip the breaker after five minutes due to various factors, including:

  • Electrical overload
  • Dirty air filters that restrict airflow
  • Refrigerant leaks that cause the compressor to overheat
  • Faulty capacitors or relays that draw excessive current
  • Compressor issues
  • Faulty wiring that leads to short circuits
  • Extreme weather conditions
  • Internal AC unit problems.

These issues can disrupt the normal function of the air conditioning system, leading to repeated breaker trips to prevent electrical damage or fire hazards. Identifying and addressing the underlying cause is essential to ensure the safe operation of your AC unit.

7 Common Causes of Your AC Breaker Tripping

Clogged air filter.

A clogged air filter is a common culprit of AC breaker trips. When the air filter becomes clogged with dust, dirt, and debris, it restricts airflow to the AC system. As a result, the system has to work harder to pull in air, causing increased strain on the components. This additional strain can lead to overheating, particularly in the compressor and motor, which may cause the breaker to trip to prevent damage or electrical hazards.

Regularly changing or cleaning the air filter helps prevent this issue and ensures proper airflow, reducing the likelihood of breaker trips and extending the lifespan of your AC system.

Dirty Condenser Coils

Condenser coils dissipate heat from the refrigerant, allowing the AC system to cool your home. However, when the condenser coils become coated with dirt, grime, and debris, their ability to transfer heat is compromised. As a result, the AC compressor must work harder to maintain the desired temperature, leading to increased energy consumption and strain on the system. This can cause the compressor to overheat and trip the breaker as a safety precaution.

Regularly cleaning and maintaining the condenser coils helps prevent this issue, ensuring optimal performance and minimizing the risk of breaker trips.

Worn or Broken Coil Fan

The coil fan, located in the AC system’s outdoor unit, plays a vital role in dissipating heat from the condenser coils. If the coil fan becomes worn out or malfunctions due to wear and tear, debris accumulation, or electrical issues, it may fail to remove heat from the coils. The AC compressor may run hotter than usual, leading to increased power consumption and strain on the system, which can trigger the breaker to trip to prevent further damage.

Regular inspection and maintenance of the coil fan will help you identify and address any issues early on, reducing the risk of breaker trips and ensuring efficient cooling performance.

Faulty Parts or Wiring

Faulty electrical components or damaged wiring within the AC unit can cause electrical faults or short circuits, which may lead to breaker trips. Common culprits include defective capacitors, relays, contactors, or wiring issues such as frayed or corroded wires. When these components malfunction, they can disrupt the normal flow of electricity within the system, causing the breaker to trip as a protective measure.

Have a qualified HVAC technician inspect and repair any faulty parts or wiring to ensure the safe and reliable operation of your AC system.

Low AC Refrigerant

Refrigerant is essential for the cooling process in your AC system, absorbing heat from indoor air and transferring it outside. If the refrigerant levels are low due to leaks or improper charging, it can affect the system’s ability to cool effectively. Low refrigerant levels cause the AC compressor to work harder to achieve the desired temperature, leading to increased energy consumption and strain on the system. This can result in an overheating compressor and subsequent breaker trips.

Professional inspection, leak detection, and refrigerant recharge are necessary to address this issue and prevent further damage to your AC system.

Frozen Evaporator Coil

A frozen evaporator coil is a common issue that can lead to AC breaker trips. When warm air from your home passes over the cold evaporator coils, moisture in the air condenses and freezes on the coils’ surface. This ice buildup restricts airflow and reduces the system’s ability to absorb heat, causing the AC unit to run continuously to achieve the desired temperature. The increased workload can lead to an overheating compressor and motor, triggering the breaker to trip as a safety precaution.

Thawing the evaporator coil, identifying and addressing the root cause of the freezing (such as low refrigerant levels or restricted airflow), and regular maintenance can help prevent this issue and ensure the efficient operation of the AC system.

Grounded Compressor

A grounded compressor occurs when the electrical winding inside the compressor comes into contact with the outer casing, creating a ground fault. This problem can happen due to insulation breakdown, compressor motor failure, or physical damage to the compressor. When the compressor becomes grounded, it can cause a short circuit or electrical overload, leading to the breaker tripping to prevent electrical hazards or damage to the system.

Fixing a grounded compressor requires professional diagnosis and repair by a qualified HVAC technician to ensure safe and efficient AC operation.

Why Does My AC Keep Tripping the Breaker?

a breaker box

The AC is our best friend on blistering hot days. But it can also be our worst enemy if it keeps tripping the breaker and interrupting our cold air supply. It can be tempting to keep resetting the breaker so you can feel comfortable again, but that will only do more harm.

So, what should you do if your AC keeps tripping the breaker? Here are some ways to troubleshoot the issue and enjoy cool air again. If none of them work, there’s a more complex underlying problem that requires the attention of a pro. Contact an HVAC specialist who can get to the root cause and fix it.

What To Do If Your AC Keeps Tripping the Breaker

Breakers are safety devices in your home that prevent short circuits and overloads. Your AC’s breaker will trip when the unit pulls in more amps than the breaker can take. For example, a 20-amp breaker will trip if the AC uses 30 amps. It trips to protect the AC from damage and prevent a house fire.

Here are the most common reasons that cause your AC to trip and what you can do about them.

Dirty Air Filter

A dirty air filter is the culprit behind many AC issues, including a continuously tripping breaker. If your AC’s filter is full of dirt and debris, that will hamper airflow and cause the unit to overheat. Your AC has to work harder and longer to circulate air inside its system, causing it to use more electricity and overheat. That’s when the breaker will step in and trip.

This issue is easily preventable if you regularly replace your filter. Clean or replace your AC’s air filter every three months. You might have to do so more frequently if you share your space with furry family members.

Dirty Condenser Coils

The condenser in your AC’s outdoor unit dissipates the heat collected from your home. But it can’t do its job if there’s grime all over the condenser coils. Your AC will keep working to disperse the heat, pulling in more and more electricity. That will cause a short circuit, and the breaker will trip.

Schedule yearly AC tune-ups with an HVAC professional to prevent this issue. The HVAC technician will have the right cleaning products and tools to restore your AC’s condenser coils to their original state. Your AC can work efficiently again without constantly tripping the breaker.

Damaged Coil Fan

Your AC has a coil fan that blows air over the coils, dissipating heat from inside the unit. The coil fan runs on a motor that wears down over time and becomes less efficient. It’ll start consuming more energy and eventually burn the fan out. The jump in electricity usage can trigger the breaker to trip.

Replacing a coil fan motor is a complex task, even for homeowners with some DIY know-how. Let an HVAC specialist handle the necessary repairs or replacements. Your AC will be running smoothly again sans any breaker trips.

Malfunctioning Compressor

The AC compressor plays a crucial part, pressurizing the refrigerant and increasing its temperature as it passes through the system. However, the compressor can develop start-up issues over time and consume more energy than usual. That explains why the breaker keeps tripping.

Your AC should turn on in a second or two, but you likely have a compressor issue if it takes longer or your AC doesn’t turn on . Get professional help if you’re experiencing this. The HVAC specialist will assess the situation and provide the best solution, including replacing the compressor if it’s beyond repair.

Wiring Issues

Your AC may be simple to use, but there’s a complicated system of wires inside. These wires can become loose over time and cause electrical arcing. This is when the current jumps across a gap in the circuit, and it can lead to a house fire. If your AC’s breaker keeps tripping, faulty wiring might be the reason.

Never attempt to fix wiring issues yourself, even if you’re confident about your DIY skills. Let HVAC professionals handle this task. They will re-wire the circuit safely and have your AC running at its best again. They might also install a new metal plate to house all the wires.

Refrigerant Leak

Low refrigerant is another possible reason your AC’s breaker is constantly tripping. When your AC has insufficient refrigerant, it can’t handle large loads and your AC won’t be able to cool enough . The breaker will sense the danger and trip as a safety measure. A leak in the system can cause the refrigerant level to fall below the required amount needed for the AC to run efficiently.

A refrigerant leak isn’t something to take lightly. Prolonged exposure to refrigerant is hazardous to human health. Get professional help immediately if you suspect a refrigerant leak. An HVAC specialist will find and patch up the hole or replace the damaged component.

Most AC issues related to a tripping breaker are complex. Even the most experienced DIYers may not have the tools and skills to resolve them. Instead of stressing, sit back and let an HVAC specialist do the work. The technician will identify the root cause and resolve it before it snowballs into a more costly problem.

Dirty Condenser Coil Symptoms to Look Out For

Dirty condenser coils can spell trouble for your AC. They can cause various issues, leaving you hot and stuffy inside your home. It’s normal for your AC’s condenser coils to accumulate dust, dirt and debris over time. Here are some signs it’s time to have it cleaned.

Your Utility Bills Are Soaring

If you use your AC regularly, you probably know how much energy it consumes monthly. If your utility bill is higher than usual, that’s a sign of a clogged condenser coil. It’s hampering your AC’s efficiency and driving up its energy usage. Regular coil cleaning should boost your AC’s performance and return your utility bill to normal.

Your Unit Is Working Longer

Is your AC taking hours to cool your space down when it only needed half an hour before? You hear the blower running tirelessly and the ducts spewing air, but you still don’t feel any relief. If your unit has to work longer, its condenser coil might be dirty and hampering efficiency. That can cause the AC’s components to wear down, shortening its lifespan.

It Does Not Feel As Cool

The whole point of having an AC is to feel comfortable even on the hottest days. It’s frustrating when the AC is on but you still feel hot and miserable. If your AC fails to cool down your home, the condenser coil probably needs a thorough cleaning. Dirt is likely trapping the heat in the condenser coil, explaining why your AC is blowing warm air.

The Condenser Coil Is Frozen

Dirt and condensation are a bad combination to have on a condenser coil. It can cause the coil to freeze, preventing it from dissipating the heat inside your home. The result is an AC with no cooling capabilities. If your AC’s condenser coil looks icy, that’s a sign that it’s dirty and needs professional cleaning.

It Feels Humid Inside Your Home

High humidity levels at home can leave you feeling sticky and uncomfortable. But that’s not the worst of it. It can also lead to water damage, mildew growth and health problems. If your AC can no longer remove the excess moisture in the air, its condenser coils are probably clogged. Cleaning it should help with your humidity issue at home.

If you notice any of these signs, do your AC and yourself a favor and have a professional come clean the condenser coils. HVAC technicians will remove all the dirt and debris to restore the condenser coil’s function. Your AC will run more efficiently, and you’ll feel comfortable in your home again.

What Is a Grounded Compressor and What Causes It?

The compressor plays a crucial role in the AC system, pressurizing, heating and cooling the refrigerant. Unfortunately, compressors only have a lifespan of 10 to 15 years and will eventually fail. It’s not uncommon for homeowners to experience a grounded compressor or a compressor short to ground.

That happens when the compressor’s electrical winding breaks and hits the compressor’s side. That causes the oil to leak and ignite, leading to a compressor short to ground. It’s an electrical phenomenon where the electric current within a circuit redirects itself to the ground.

Compressor issues are for the pros to handle. Contact an HVAC specialist to replace your compressor and inspect the refrigerant lines.

Let the Pros Solve Your AC Troubles

Many homeowners have a love-hate relationship with their AC. It’s great when it’s working but frustrating when it’s acting up. If your AC has been stressing you out, HVAC professionals can help take the load off your shoulders. They will sort it out and get your AC performing at its best again.

Why does AC Circuit Breaker Keeps Tripping and How to Fix It

why-does-ac-cirtuit-breaker-keeps-tripping-alphamechanicals-blog-post

Is your ac unit constantly tripping the circuit breaker ? Do you find it in constant need of repair? In this article, we break down the cause and effect behind problems with an AC unit’s circuit breaker, and solutions you can use to fix the problem.

What can cause an AC tripping circuit breaker?

Are you wondering “Why is my air conditioner tripping the breaker?” A circuit breaker can fail or trip for a variety of reasons. A few of the main culprits could be:

The breaker could be unreliable

While rare, a once-sturdy and reliable switch can weaken over time and trip, or even stop working entirely. This is easily solved by buying a new one and replacing the switch , either yourself or at the hands of a professional technician.

The compressor and/or fan can draw too many amps

This problem can have a variety of causes:

For example, if a motor gets stuck and doesn’t react properly to applied voltage, it will pull more amps. This can cause heat to generate in the wiring and cause the ac unit tripping breaker. While not tripping it automatically, it can trip when the thermostat signals the AC to turn on.

This pattern often happens with the compressor when the cool season starts . The compressor pumps refrigerant through the lines, and when this component fails or works irregularly, it can cause problems with the circuit breaker as well.

If the capacitor is in working order, adding a hard-start capacitor to the circuit can give it the boost it needs to spin the motor and get things going. Beware, however; this is an indication of a failing unit. Consider budgeting for a new compressor or ac unit, as it may fail at an unexpected time.

Short circuiting

A breaker can also trip because of an electrical short . This is caused when hot wire touches a path it’s not supposed to, such as a neutral wire. When the system is on and the power is active, the system can overload and the breaker can trip. The breaker will instantly trip when voltage is applied.

Touching wires

The breaker will also trip if a wire from the motor touches the inner walls of the compresso r. The windings within the motor help spin the motor sheath, and these windings should be covered to shield the wiring. However, this is still a cause, primarily on older systems that have been active for 10-20 years or longer. The electricity grounds into the floor, and the ac unit keeps tripping breaker.

Incorrect refrigerant pressure

Refrigerant pressure at the wrong level can trip the AC breaker and cause other trouble. High levels of refrigerant pressure causes the compressor to strain to work properly, causing a breaker trip eventually. This problem is rarer than other ones, but can look like a bad compressor.

How to solve problems when AC keeps tripping breaker

When the breaker is unreliable.

This problem is easily solved by buying a new breaker and replacing the switch, either yourself or at the hands of a professional.

Look for identifying signs of short circuiting: visible burns on wiring, burning smells, or flickering lights. Confirm potential shorts with a multimeter.

When wiring is out of place

If a breaker is tripping because exposed wires are touching the inner walls of the compressor, covering the exposed wires will shield the current.

When refrigerant pressure is incorrect

Removing a pound of refrigerant should indicate a pressure issue, and your gauges should vary a bit. If this happens AND the temperature splits hovers between 18-22 degrees, you can remove refrigerant until the compressor amps drop below the RLA, and the temp split remains within range. If removing the refrigerant isn’t working, you might want to replace all the old refrigerant with virgin refrigerant and a factory charge. If you’ve done this and checked all other components on the system, and the compressor still pulls high amps, you have a bad compressor.

These are just some of the reasons your home’s circuit breaker would trip the breaker in the main electrical panel. If it trips immediately when turning it back on, it is likely a wiring problem. If it trips after a certain time period, there is an issue with a component in the AC system.

Let a professional do the fixing. We don’t advise that anyone take on these problems by themselves, and as a matter of fact, you might not even be able to purchase the parts you need for a DIY fix. Contact a profession to diagnose and fix the problem for the best possible outcome.

Looking for a quality AC repair in Sacramento Area?

How can maintenance prevent my AC tripping breaker?

Active maintenance on your AC unit will prevent wear and tear on the unit, and extend both its lifespan and quality. Think of an AC unit as a car engine; changing the oil or filling the tires can help prevent much larger issues later on. In the same way, monitoring your HVAC system can help prevent large-scale over time. To solve the question of “Why does my air conditioner breaker keep tripping,” we outline below how you can actively clean and maintain your AC unit.

To begin, read the manufacturer manual

If you don’t have a paper manual, you may be able to find it online. Make notes of maintenance periods and dates for your ac unit and all other components of your HVAC system; chillers, boilers, motors, etc. These manuals provide a standard for your HVAC upkeep, and work to keep your house in proper order.

To clean off the external unit: (Condenser and Compressor)

Power off the main unit.

When cleaning the ac unit, you want to ensure no power is traveling through it. You can either remove the breaker/block or move the switch to the off position. If this isn’t possible, you can also switch off power to the AC condenser at your main electrical panel.

Clear debris in and around the unit

Most debris will get stuck in the condenser fins, and this area needs to carefully be cleaned away. You can use a rough paint brush to deal with easy-to-remove debris, and follow up with your vacuum and brush attachment. Remove debris and plant growth that is within 2 feet of the unit.

Clean and straighten the AC fins

Fins can collect debris that is not easily removed with a brush. Instead, an old knife can scrape out debris that is stuck between the fins, and reshape any damaged or bent fins.

Clean the condenser fan

This is another area where debris needs to be cleaned regularly. This component can be wiped with a damp cloth and left to dry in the sun.

Cleaning the fins inside out

The best way to clean the fins is by spraying them with a garden host. This removes caked-on dirt that other methods wouldn’t dislodge. Take care to not get water on the fan motor, and if the motor doesn’t have sealed bearings, check the fan lubrication as well. A few drops of electric motor oil should work nicely.

To clean the internal unit: (Evaporator and Blower)

Clean the evaporator coil.

The evaporator coil door can be found inside the blower/furnace unit and accumulates lots of debris. Use a soft brush to remove dust, then spray with a no-rinse coil cleaner to remove other gunk and improve efficiency.

Clean the evaporator drain

The evaporator drain can get clogged due to algae and mold buildup, and needs to be unplugged. A clogged drain can cause flooding and stop the unit from functioning until the water is drained. Clogs can also cause odor to build up and leak from the unit. A wet/dry vacuum cleaner can remove debris from the evaporator drain.

Change the blower filter

This step changes depending on where you live. In dusty environments (such as here in Sacramento), filter changes are necessary more often, typically right before the starting of the “heating” and “cooling” seasons. The filter is typically found at the end of the fresh air return duct.

Completing all these steps should ensure your HVAC and AC unit stay clean and regulate temperature more effectively. When all parts are dry and in place, you can turn on the power and test that the unit works correctly. This maintenance will prevent issues where the air conditioner trips circuit breaker.

Why Does My Air Conditioner Keep Tripping the Circuit Breaker?

View from top of air conditioning unit

Did your AC suddenly shut off? Has your circuit breaker tripped?

If that just happened for the first time, reset the breaker and see if it trips again when you run your AC. If it doesn’t trip again, everything's probably fine.

But if the breaker does trip after you reset it, something’s not right. In this case, don’t try resetting it again.

Your circuit breaker is likely tripping because of these two reasons:

  • Circuit or wiring issues.
  • Your AC is using too much power.

We’ll go into more detail about both of these causes and what you can do to stop your air conditioner from tripping the circuit breaker.

Let’s start with circuit/wiring issues.

Cause #1: Circuit or Wiring Issues

The reason why your circuit breaker keeps tripping may not have anything to do with your AC at all. The problem could be with your circuit breaker and home wiring.

Circuit breaker panel wires

Wires in a circuit breaker panel

Loose Electrical Connections

Your breaker box has many connecting wires that can become disconnected or loose over time. Temperature changes cause wires to expand and contract, which is what makes them come loose.

Solution: An electrician will need to tighten the connections and replace any faulty wires.

Bad Circuit Breaker

A residential circuit breaker

Your circuit breaker protects your home from electrical damage. With general wear and tear, breakers can go bad over time, too. You’ll know your circuit breaker is bad if you notice these signs:

  • Circuit breaker is hot to the touch.
  • Burning odor around the breaker.
  • Black burn marks on the breaker.
  • Frayed wires.

Solution: Contact an electrician to take a look at your circuit breaker. For safety reasons, you shouldn’t attempt any electrical repairs on your own home. Electrical problems require the skills and safety of a licensed electrician.

Cause #2: Your A/C is Using Too Much Power

Let’s say your electrical equipment is fine. The next step is to look at your AC, as it could be the culprit that’s causing your circuit breaker to trip.

Your AC will trip the circuit breaker if it’s drawing more amps than your breaker can handle. What causes your AC to draw too many amps?

There are many problems that cause your A/C to overheat and draw more power. Let’s go into a few of the most common issues.

Low Refrigerant, or a Leak

If your AC is leaking refrigerant, your AC will have to work harder, and use more power, to cool your home’s air.

Solution: Contact a licensed professional to replace your AC’s refrigerant and repair any leaks.

Bad Capacitor

Air conditioning unit with red arrows pointing at capacitor location

If your air conditioner is having trouble starting before the circuit breaker trips, it points to a bad capacitor. A capacitor is responsible for starting the compressor, and if the compressor has trouble starting, it could pull too many amps and trip the breaker. Sometimes capacitors wear out, so they’ll need to be replaced.

Solution: Contact an AC contractor to replace the bad capacitor.

Shorted Motor

Electric motors in your AC can run for a long time. But if a motor runs for too long, the insulation around the wires can deteriorate and cause an electrical short.

A short is when electricity bypasses its normal path like taking a shortcut, which allows more electricity to flow than the wires can handle. If you have a short, your circuit breaker will trip to prevent damage to your home and AC equipment.

Solution: With any electrical repairs, whether with your AC or home, need to be handled by a professional. Contact an HVAC contractor to determine if you have a shorted motor.

Grounded Compressor

A grounded compressor is the worst-case scenario on this list. Similar to a short, a grounded compressor occurs when an electrical winding within the compressor hits the side of the compressor. This causes a direct short to ground, which ignites the oil in the compressor and causes a burnout.

Before this starts a fire, your circuit breaker will shut the electrical current off, which is what causes your breaker to trip.

Solution: The bad news is if you have a grounded compressor, you’ll have to replace the compressor, which is more expensive, or the whole outside unit. If your compressor isn’t covered under warranty and your outside unit is old, it may make more sense to replace the outside unit instead of the compressor.

Why is My AC Tripping the Circuit Breaker?

October 04, 2021

why breaker trips on ac

Air conditioners are vital to Floridians, so it's no surprise that homeowners would be stressed if their AC suddenly started turning off.

If this is happening to you now, it’s likely a tripped circuit breaker. When your AC trips the circuit breaker after running for only a few minutes, your breaker cuts the power to the AC system.

Why is your AC tripping the circuit breaker? Many issues can be at play, but the primary 3 reasons include:

  • An overloaded circuit
  • A grounded compressor
  • A faulty breaker

We’ll review how to reset your circuit breaker to see if that restores your AC’s power. If it doesn’t, we’ll dive into the potential problems related to a tripped circuit breaker and how to troubleshoot them.

Want a professional to identify and fix your AC’s tripped circuit breaker? Contact Advanced Air for an AC repair . We provide punctual and round-the-clock service .

Reset your circuit breaker

why breaker trips on ac

Reset your circuit breaker to see if it stops tripping

Before we look at what could be causing the frequent tripping, let's first try resetting the circuit breaker. You can do so by:

  • Let the unit cool down for about 5 minutes. The Department of Energy recommends letting the unit rest before resetting any breakers.
  • Turn off your thermostat.
  • Locate your gray main circuit panel by checking your closets, garage, or basement. Make sure there's no water on the ground in the room with the panel. If there is, do NOT stand in the water while resetting the breaker.
  • Find the AC switch. The breakers are typically labeled. If not, look for the switch that is either in a middle position or OFF. Some manufacturers have a visible color indicator that shows that a breaker has tripped.
  • Push the switch OFF unless it's already OFF. If already OFF, skip to Step #6.
  • Push the switch ON. You should feel a satisfying click into place.
  • Wait for 30 seconds.
  • Turn your AC back on to test.

If your AC immediately trips again, do NOT reset the breaker again until the cause is corrected. Multiple overcurrents, or surges of electricity, can damage your AC and even start a fire.

Read on to learn about the potential issues causing your AC to trip the circuit breaker.

Three main reasons behind your AC tripping the circuit breaker:

1. an overloaded circuit.

Circuit breakers shut off the flow of electricity whenever the number of amps (a unit of electrical current) exceeds its amp rating. For example, if the circuit breaker has a rating of 15 amps, it'll trip whenever 20 amps flow through the circuit.

So, whenever your AC is using too much energy, it's pulling in more amps than usual, causing a surge and your circuit breaker to trip.

Your air conditioner can use too much energy if:

The air filter is dirty:

Why is My Air Filter Black?

An Advanced Air technician can help you replace your filter

Air conditioners need air to be flowing into the system to cool your home enough to meet your set temperature.

When air filters get clogged with debris and dirt, they block airflow from entering the system. Your AC now has to compensate by working harder and using more electricity to cool your home. The circuit breaker isn’t used to this amount of energy consumption and trips to protect your AC.

The condenser is dirty:

why breaker trips on ac

Our technicians can help clean your condenser

Your AC's outdoor unit is called the condenser. It plays an essential role in keeping your home cool by dumping the heat your indoor unit absorbs from your home's air outside.

When the condenser is dirty or blocked by bushes, your outdoor unit can no longer effectively transfer the heat outside, and your AC has to use more energy and take longer to cool your home. This increase in needed power trips the circuit breaker.

The condenser fan doesn't work correctly:

As we mentioned above, the condenser is your outdoor AC unit. The condenser's fan helps dissipate heat back outside. If you stand next to the condenser and can't hear the fan rumbling, it's likely broken.

When the fan’s motor is broken or worn out, the electricity from your AC system to the motor has nowhere to go and is flowing freely. Your AC will automatically detect this issue and trip your circuit breaker to prevent the wires from frying and damaging your system or home.

The refrigerant is leaking:

What is refrigerant? It's a cold substance in your AC that helps the indoor unit absorb heat from the air. Leaking refrigerant means your AC can't cool your home as effectively due to reduced heat absorption abilities, forcing it to use more power and tripping the breaker due to overload.

How do you know you have a refrigerant leak? You can tell when:

  • You see ice forming on the condenser
  • You hear hissing or bubbling noises coming from your inside AC unit
  • You have higher than normal monthly energy bills

why breaker trips on ac

Advanced Air technicians can diagnose the problem behind your circuit tripping

If you suspect your breaker keeps tripping because of any of these reasons, try changing out your air filter monthly and booking an appointment with an AC technician to clean the condenser. Also, make sure to check your condenser's fan and inspect the refrigerant lines.

2. A shorted compressor

Typically, electricity flows in a loop called a circuit. When a compressor "shorts," it's because a malfunction interrupts the loop, allowing too much electricity to flow through the circuit. The circuit breaker then trips to shut off electricity to prevent the overload from potentially causing a fire.

Most malfunctions are because of a winding, where electrical currents pass through inside the compressor, breaking and not being able to handle its load anymore. The additional electricity ignites the oil in the compressor, causing a sudden current surge that burns out the compressor and forces the circuit breaker to trip.

Unfortunately, a burned-out compressor most likely needs to be replaced because a functional compressor is vital as it pumps refrigerant throughout your system.

Replacing the compressor can be expensive if you don't have a valid warranty. If you have a valid warranty, financing options can help. Or, you might want to look into replacing your system entirely. You can use our handy AC installation cost calculator to see if a replacement would be more cost-effective than replacing your compressor.

3. A faulty breaker

why breaker trips on ac

A damaged circuit breaker

Your circuit breaker may keep tripping because of an issue with the breaker itself.

To determine if the breaker is damaged, find your home's main circuit panel and look for indicators that you have a faulty breaker, such as:

  • The breaker is hot when you touch it
  • You can smell a burning odor near the breaker
  • You see loose connecting wires
  • You see burn marks on the breaker
  • You see obvious worn-out parts

If you notice any of the above indicators, you're dealing with a faulty breaker that needs professional replacement. Call a technician immediately.

First, do not continuously reset your AC circuit breaker! Now, you may want to isolate the origin of the issues. After that, you can establish whether it's an issue that you can address yourself or requires the attention of an HVAC repairman.

Learn more about dealing with an air conditioning unit that continuously gives you trouble and when to call in a professional AC technician.

What To Do When your AC Keeps Tripping the Breaker: Step 1

To begin diagnosing your system's problem, follow these steps:

  • Turn off whichever AC system keeps causing the circuit breaker trips (including its thermostat functions)
  • At the tripped panel, turn back on the tripped circuit.
  • You want to wait at least 30 minutes with the AC off! It's essential to ensure any thermostat-controlled systems on the AC are also turned to the off position, so the internal systems within the system are not triggered.
  • After waiting for a period that exceeds at least 30 minutes, turn the system back on.

Possible Results:

It continues to operate without tripping the circuit breaker.

That's great news! The AC tripping issue that led to the power surge was most likely a rogue issue that won't necessarily be repeated. Problems like these are primarily out of your control and external to the household, such as lightning. If the circuit breaker doesn't trip again, it has successfully performed its function, and you can continue enjoying your cool home without worries.

It Works for a While, Then Trips Again

There is still hope that you can still safely address this issue yourself. Try replacing your air conditioner's air filter. A dirty air filter can cause the entire AC system keeps tripping the breaker, leading the unit to draw more power than is safe. This leads to a power overload and a circuit breaker trip. An AC air filter can usually be easily replaced by its owner. Check your system's instruction manual on how to complete that process.

It Immediately Trips Again

If the AC immediately trips the circuit breaker again, the problem has been successfully isolated to your outside AC unit. It is now the time to call in a professional air conditioner repair company to deal with many possible issues why your AC keeps tripping the breaker. Continue reading to learn more about those potential issues.

Why Your AC Circuit Breaker Keeps Tripping

There are several reasons your system is having this problem, including:

  • A condenser coil is covered in dirt, debris, and grime.
  • A physical component of your AC's electrical system could be loose or damaged.
  • The AC's fan motor has issues that could lead to a power overload.
  • An evaporator coil may not be releasing heat as it should.
  • Damaged lines that cause a refrigerant leak.
  • The AC compressor failed.

Learn more about these problems and how you can identify them, so you know what to tell an HVAC technician when they arrive.

Dirty Condenser Coils

Have you noticed your air conditioner hasn't been cooling your home as well as when you first had it installed? This might be tied to why your AC system keeps tripping the breaker. If you've noticed a gradual decrease in your air conditioner's functionality, the issue is most likely dirty condenser coils.

The condenser coil's function is to create a way to release heat gathered by the AC, expelling it outside of your building. It's located in the part of the outdoor unit of your household. Due to its location, the coil can become covered with dirt and other debris from natural elements. When this occurs, the system must work harder to maintain performance.

An overworked system will attempt to draw more power and be the reason why your AC system keeps tripping the breaker. Neglecting to have necessary regular maintenance done is likely why your AC keeps tripping the breaker.

For the reasons concerning high voltage stated above, a professional is required to address this issue.

Failure of an Electrical Component

An electrical component failure within your unit is a catchall phrase referring to many possible scenarios that could be the reason why your AC circuit breaker keeps tripping. Electrical wiring could have become frayed, too much power was sent to the unit, or an electrical short may have cut its function.

Pinpointing why your AC system keeps tripping the breaker requires specific electrical tools and can be dangerous to perform independently. However, identifying the problem could save you from the costly decision to replace the entire system.

You must reach out to a professional to perform this high-level assessment of your air conditioner's electrical system due to its complex nature and potential risks.

The Motor for Your Air Conditioner's Fan Has Malfunctioned

Moreover, the same elements that may have affected your condenser coil can also put pressure on your air conditioner fan's motor. The result leads to your AC system fan not spinning as we are common to seeing.

When any part of an electrical system has to work harder to overcome obstacles, it will draw too much electricity to remain proficient in its function. This could be the reason your air conditioner tripping the breaker.

As you know by now, this tendency to draw more power than is safe will lead to your circuit breaker to trip to safeguard the entire household's electrical system. This diagnosis with your AC blower motor for why your AC keeps tripping the breaker often comes with a repair that requires a professional to address because of the fan's proximity to high voltage components.

The Air Conditioner Evaporator Coils are Frozen

Have you noticed ice on your air conditioning system coils? This could be the reason your AC circuit breaker keeps tripping.

If you've neglected to have annual or biannual maintenance done on your air conditioner system, debris may have caused there to be reduced airflow in your system. This can lead to the freezing of the evaporator. Again, the system attempts to compensate for these obstacles by drawing more power. Your home's circuit breaker will trip to safeguard the entire system.

Refrigerant Leaks

Older systems whose owners have neglected to perform maintenance may have developed leaks in refrigerant lines. This corrosion is part of the natural wear and tear that comes with time.

Over time, the level of the refrigerant fluid will drop, and you will notice a decline in your air conditioner unit's performance. Your air conditioner circuit breaker keeps tripping because it's attempting to overcompensate, leading to the circuit breaker trip.

Compressor Failure

Your grounded compressor failing is the most catastrophic of the potential issues, causing your air conditioner to keep tripping the circuit breaker.

Not only could this be the reason your air conditioner's circuit breaker keeps tripping, but a compressor's failure often results in a need for unit replacement because of its overall importance to the entire air conditioning unit's function. Again, this is an issue that can be extremely dangerous for untrained individuals to attempt to repair.

A Safety Warning

All these potential causes for why your AC breaker trips require a trained professional HVAC contractor specializing in air conditioners or a certified electrician. All the repairs to these individual elements of the AC involve high voltage and can be dangerous undertakings.

Don't attempt to address any of these issues relating to why your ac system keeps tripping the breaker yourself, as this can be highly unsafe. Please get in touch with an HVAC professional.

However, as a responsible owner of an AC unit, you should seek to know more about why your air conditioner system keeps tripping the breaker. According to FEMA, twenty-four thousand residential electrical fires are reported yearly in the United States alone.

Some of the issues that are the exact reason your AC is repeatedly tripping the breaker could also lead to a fire that could have been prevented with annual or biannual maintenance by a professional.

The Importance of Regular Maintenance

If your AC system keeps tripping the breaker, it's likely related to an overdraw of power. If the problem doesn't fix itself after the 30-minute reset and air filter swap, it's time to reach out to a professional HVAC technician.

Breakers trip from time to time, and a one time power surge can cause excess power to shut off everything in a home. A bad circuit breaker or a cooling system that pulls more electricity than is required is not only bad for your home, but a real safety risk.

The good news is that many of these common problems can be avoided with regular AC system maintenance . If you never want to deal with an AC system and a tripping breaker, reaching out to a professional AC tech to have a look is still a great idea.

This may save you money in the long run and help further ensure your household's safety from dangerous consequences.
