All diagnoses and test are on the frnot of that small panel. That's it buddy. This POS does not tell you what failed. It just says "cool fail" or "heat fail" by measuring voltage between terminal 6,7,8. Even those blooming idiots from trane could not tell what part caused the failure. They say "cycle the power and hope for the best"

Will check Trane voyager manual and let you know if i find anything that helps!!!

It`s better to be silent and thought the fool; than speak and remove all doubt.

Thanks for the info!!!

I guess the info was removed? Having a hard time finding this paperwork or PDF!

nothing in that profile indicates you are a service tech, more than likely, I removed it after giving them enough time to see it generally will not put tech lit in open forum, never know who's lurking out there

good luck ..... worst ignition system in the trade by far.....

it was working.... played with it.... now its broke.... whats the going hourly rate for HVAC repair

Moved to tech to tech commercial

Do you still have the info on the voyager,buddy?

I too would love some info on this board. Apparently it offers several configurations for wiring and operation, but info is very scarce.

Pro members should seek Pro info in the Pro forum.

Trane Defrost Control Board LED Codes | Solve Common Issue!

If your Trane furnace is equipped with a defrost control board , you can use the LED codes to help troubleshoot any problems that may arise. The most common code is the “red flash” which indicates that the board is in defrost mode.

Other codes include the “green flash” which means that the furnace is operating normally, and the “amber flash” which indicates a problem with the igniter.

Trane Defrost Control Board LED Codes

The Trane Defrost Control Board is a crucial component of HVAC systems that helps to regulate the defrost cycle, ensuring the efficient functioning of the system. The board is equipped with LED codes that allow troubleshooting and identification of issues that could arise during operation.

The codes and their meanings are as follows:

• Steady Green LED – The system is operating normally.
• Steady Red LED – The defrost control board has detected a fault and is in lockout mode.
• Flashing Red LED – The sensor is not detecting proper temperature, indicating a possible faulty sensor or a wiring issue.
• Flashing Green LED – The system is in defrost mode, and the board is actively monitoring the process.
• Steady On – Power is present
• Flashing Slowly – Normal operation
• Flashing Rapidly – Defrost is active
• Two Flashes – High-pressure switch open
• Three Flashes – Low-pressure switch open
• Four Flashes – Auxiliary limit switch open
• Five Flashes – Outdoor temperature sensor fault
• Six Flashes – Reversing valve fault
• Seven Flashes – Defrost control board fault

Understanding these LED codes is crucial for HVAC technicians to identify and resolve any issues that may arise in the Trane Defrost Control Board.

What are the Codes for a Trane Furnace?

There is no one-size-fits-all answer to this question, as the codes for a Trane furnace will vary depending on the model and year of your furnace. However, you can generally find the code information for your furnace in the owner’s manual or by contacting Trane customer service.

How Do You Test a Trane Defrost Board?

There are a few things that you need to do in order to test a Trane defrost board. The first thing that you will need to do is locate the board. Once you have found the board, you will want to remove it from the unit. Next, you will want to check for any visual damage on the board. If there is any damage, you will want to replace the board. If there is no visual damage, you will then want to connect a multimeter to the board. You will want to set the multimeter to ohms and check for continuity between the two terminals on the board. If there is continuity, then the board is good. However, if there is no continuity, then the board needs to be replaced.

What Causes a Hard Lockout on a Heat Pump?

A hard lockout on a heat pump is caused by a number of different things. The most common cause is when the outdoor temperature drops below the minimum set point for the heat pump. This can be caused by a number of different things, including a cold front moving in, or simply the temperature dropping at night. When this happens, the heat pump will shut off completely in order to prevent damage from happening to the unit. Another common cause of a hard lockout is when the indoor temperature sensor fails. This can cause the heat pump to think that the indoor temperature is too low, even when it isn’t, and as a result, it will shut off. Finally, if there is a problem with the outdoor fan, this can also cause a hard lockout. If the fan isn’t able to turn on, then the heat pump won’t be able to circulate air properly and it will shut down in order to prevent overheating.

What Does Hard Lockout Mean on a Trane Heat Pump?

If your Trane heat pump is locked out, it means that the system has been turned off and can’t be restarted until a qualified technician resets it. This usually happens when the system detects a problem that could cause damage or harm, such as an overheating condition.

Once the problem has been resolved, the lockout can be reset and the heat pump will operate normally again.

Trane 4Twr4 Fault Codes

If you’re a Trane 4TWR4 owner, you know that these units are some of the most reliable and durable on the market. But even the best units can develop faults over time. If your 4TWR4 is displaying a fault code, it’s important to know what that code means so you can take steps to fix the problem. There are four main fault codes that your 4TWR4 may display:

• Code 01: This indicates that there is a problem with the unit’s condenser fan. The most likely cause is a dirty or damaged fan blade. You’ll need to clean or replace the blade to fix this problem.

• Code 02: This indicates that there is a problem with the unit’s evaporator fan. The most likely cause is a dirty or damaged fan blade. You’ll need to clean or replace the blade to fix this problem.

• Code 03: This indicates that there is a problem with the unit’s compressor. The most likely cause is a blown fuse or tripped breaker.

Trane LED Codes

If you have a Trane furnace, you may be wondering what the different LED codes mean. Here is a list of the most common codes and their meanings:

Blinking Green Light: This indicates that the furnace is in standby mode and waiting for a call for heat. Solid Green Light: This means that the furnace is operating normally.

Flashing Red Light : This code indicates that there is an error with the furnace. The specific error will be displayed on the control panel. Consult your owner’s manual for troubleshooting steps.

Continuous Red Light: This means that the limit switch has been activated and the furnace needs to be serviced by a qualified technician.

Trane Furnace Error Codes

Trane furnace error codes are an essential diagnostic tool for identifying issues with your heating system. These codes not only help technicians identify problems quickly but also provide homeowners with the necessary information to troubleshoot issues before calling a professional.

Here are the most common Trane furnace error codes and their meanings:

• 2 flashes: Indicates a problem with the pressure switch.
• 3 flashes: Indicates an issue with the draft inducer motor.
• 4 flashes: Indicates an open limit switch.
• 5 flashes: Indicates a problem with the flame sensor.
• 6 flashes: Indicates an issue with the rollout switch.
• 7 flashes: Indicates a problem with the gas valve.
• 8 flashes: Indicates a problem with Low flame sense signal.
• 9 flashes: Indicates a problem with Igniter.

By familiarizing yourself with these codes, you’ll be better equipped to handle any furnace issues that arise.

Besides the above, you may also find the following error codes for Trane Furnace:

• 126: Internal control fault
• 131: Ignition failure
• 132: Flame sensor failure
• 133: Limit circuit fault
• 147: Low flame signal
• 151: Blower motor fault
• 161: AC power loss
• 164: Open high-limit device

These error codes can help a technician quickly identify the issue and provide a solution, ensuring that your Trane furnace runs smoothly and efficiently.

Trane Troubleshooting Guide

If your Trane unit isn’t working properly, you may be able to troubleshoot and fix the problem yourself. This Trane Troubleshooting Guide will help you identify common issues and provide solutions. First, check the thermostat to make sure it is set correctly. If the thermostat is set too low, the unit won’t run. If the thermostat is set too high, the unit will run continuously without cooling the home. Next, check for power failures. The circuit breaker may have tripped or a fuse may have blown. Reset the breaker or replace the fuse and see if that fixes the problem. If your unit still isn’t running, there could be an issue with the actual unit itself. First, check to see if there is debris blocking the air intake or exhaust vents. If so, remove the debris and try again. Next, check for freezing coils. Ice can build up on the coils and prevent proper airflow. Turn off your unit and let it thaw for several hours before restarting it again. Finally, if all else fails, call a professional for assistance.

Trane Air Handler Blinking Lights

If you have a Trane air handler in your home, you may have noticed that the lights on the unit are blinking. While this may be alarming at first, it’s actually a normal part of the unit’s operation. The blinking lights indicate that the air handler is in standby mode and is waiting for a command from the thermostat. Once the thermostat tells the air handler to start, the lights will stop blinking and the unit will begin heating or cooling your home as needed.

Trane Voyager Error Codes

If you’re getting error codes on your Trane Voyager, it means there’s a problem with the unit. Here are some common error codes and what they mean:

E01 – This indicates that the evaporator temperature is too high. Check to make sure that the coils are clean and that the air filter isn’t clogged.

E02 – This code means that the condenser temperature is too high. Again, check the coils and air filter. Make sure the unit has proper ventilation.

E03 – The third code stands for “freeze protection.” This means that the unit is sensing a potential for freezing temperatures and is shutting down to prevent damage. Check your thermostat settings and make sure the unit is in heating mode. If it still doesn’t work, call a technician. These are just a few of the most common Trane Voyager error codes . If you’re experiencing problems with your unit, don’t hesitate to call a technician or reference your owner’s manual for more information.

Trane Ac Blinking Green Light

If you have a Trane air conditioner , you may have noticed that the green light is blinking. This is normal and indicates that the unit is in standby mode. The green light will blink when the unit is first turned on, and then it will remain lit when the unit is running. If the green light starts blinking again, it means that the unit has been turned off and is in standby mode once again.

Trane Eev Control Board Troubleshooting

If you have a Trane EEV control board that is giving you trouble, there are some things you can do to troubleshoot the problem. First, check all of the connections to make sure they are tight and secure. Next, check the circuit breaker to see if it has tripped. If neither of these solutions solves the problem, you may need to replace the control board.
