Trane 90 Furnace Error Codes: What Do They Mean?
Trane 90 furnaces are very reliable. They have a high Mean Time Between Failure rate, and most users do not experience any issues. However, that doesn’t mean they can’t fail. When a Trane 90 furnace has an error, it will display an error code to alert the homeowner. These error codes are indicators of a problem with your system and tell you what needs fixing or replacing. Understanding Trane error codes are important because they alert you to potential problems before they become major issues like overheating or freezing temperatures in your home. The codes indicate where the problem lies and what needs to be fixed or replaced. Here is a list of common Trane 90 furnace error codes and their meanings:
Error Code 12
If you see an error code 12 on your Trane 90 furnace, it means there is a problem with the gas pressure. This could be because the gas pressure is too high or too low. If it’s too high, the furnace will not ignite. If it’s too low, it will not run at full capacity, and you may notice a difference in the way your house feels. It could also be because you have a blockage in the gas line. Check the gas pressure at your utility meter and, if it’s too low, call your utility company to report the issue. If it’s too high, you may need to call a professional to fix the gas line or the regulator on your furnace.
Error Code 13
This error code indicates that something is wrong with your circuit board inside the furnace. If you see error code 13, you should call a professional to replace the circuit board. The board may also have a fuse that can be replaced, but in most cases, it is a better idea to replace the circuit board entirely. Trane 90 furnaces have a circuit board inside the control panel. This circuit board is responsible for sending power to and regulating the blower, burners, and other parts of the furnace. If the circuit board fails, the furnace will display error code 13. To replace the circuit board, the furnace must be removed from the wall.
Error Code 14
If you see error code 14 on your Trane 90 furnace, it means there is a problem with the burner assembly. There may be a clog in the gas path, or there could be a problem with the regulator. The burner assembly is the piece of the furnace that lights the gas and sends heat to the rest of the system. If there is a clog in the gas path, the burner will not ignite, and you will see error code 14. To fix this issue, call a professional to clean out the gas path. If the regulator is faulty, it will not send the correct amount of gas to the burner, and error code 14 will appear. To fix the issue, replace the regulator.
Error Code 15
If you see error code 15 on your Trane 90 furnace, it means there is a problem with the ignition. The ignition is the device that ignites the gas inside the burner. This can be caused by a faulty ignition, a faulty flame sensor, or a faulty temperature sensor. The ignition is on the top of the burner assembly, and the flame sensor, temperature sensor, and stator are inside the control panel. To fix the issue, call a professional to clean the sensors or replace them entirely.
Error Code 21
If you see error code 21 on your Trane 90 furnace, it means there is a problem with the pressure switch. The pressure switch is a safety device that detects changes in pressure. If the pressure in the system changes, it will trigger the switch, and error code 21 will appear. To fix this, call a professional to replace the pressure switch.
Conclusion
Trane 90 furnaces are very reliable, but they can still have issues. When you see an error code, it is important to know what it means so you can fix it as soon as possible. Error codes let you know exactly what is wrong so you can have it fixed quickly. It is important to remember that error codes are an indicator of a problem, not the problem itself. An error code is like a red flag in the system. It tells you something is wrong, but it doesn’t tell you what. These Trane error codes are important to know if you want to keep your furnace running smoothly.
