What Does the Red Light Indicate?

The red light on the Trane XR90 furnace indicates that something is wrong with the unit. There are several different components that could be malfunctioning and causing the red light to come on. The most common cause of a red light is a faulty limit switch, which is responsible for controlling the temperature in the furnace. If this switch has failed, it will prevent the unit from reaching its desired temperature and cause a red light to appear.

Why Is My Trane XR90 Flashing Red Light?

If your Trane XR90 furnace is flashing a red light, it is likely due to one of two problems: either an issue with the limit switch or an issue with the blower motor. The limit switch monitors air temperature and prevents overheating by shutting off power when necessary. If this switch fails or becomes disconnected, it can cause a flashing red light on your furnace. The blower motor is responsible for circulating air through the system and can fail due to wear and tear over time. If it stops working, it can also trigger a flashing red light on your system.

How Do I Troubleshoot My Trane XR90 Flashing Red Light?

If your Trane XR90 furnace is displaying a flashing red light, you should first check to make sure all wires are securely connected in their respective terminals. You should also check your thermostat settings to make sure they are correctly set for your desired temperature range. If all of these components seem to be in working order, then you should check to see if there is any debris blocking airflow such as dust or lint buildup inside of the unit itself.

What Should I Do If My Trane XR90 Continues To Flash Red?

If your Trane XR90 continues to flash a red light after troubleshooting, then its likely that one of its components needs to be replaced or serviced by a professional HVAC technician. You should also inspect all safety devices such as flame sensors and pressure switches for proper alignment and operation before attempting any repairs yourself. Lastly, you should make sure that all wiring connections are secure and not corroded before calling in an HVAC technician to service your unit.
