  If your Trane Thermostat isn't heating, start by checking if the circuit breaker has tripped and reset it if needed. Ensure that the system selection is set to Heat. Verify that the heating setpoint is above the current room temperature. Also, check the fuse and replace it if it's blown. Confirm that the system switch at the equipment is in the On position. If 24 Vac is present, continue troubleshooting. Finally, allow up to five minutes for the system to respond, during which the thermostat may display 'Wait'.

  If your Trane Thermostat isn't cooling, begin by checking the circuit breaker and reset it if tripped. Make sure the system selection is set to Cool. Ensure the cooling setpoint is below the room temperature. Check the fuse and replace it if blown. Confirm that the system switch at the equipment is in the On position. If 24 Vac is present, continue troubleshooting. Wait five minutes for the system to respond; the thermostat may display 'Wait'.

  If the cooling isn't turning on with your Trane Thermostat, consider the following: * First, check for power by verifying 24 Vac between the R and W terminals. If missing, check the circuit breaker, system fuse, and HVAC equipment power switch. * Second, the thermostat's minimum off time might be active; wait up to five minutes. If needed, you can reconfigure the minimum off time in Installer Setup number 39. * Third, confirm that the system selection is set to Cool. * Finally, ensure the cooling setpoint is set to the desired temperature and is below the current room temperature.

  If the Trane Thermostat display does not come on, it might not be getting power. First, check for 24 Vac between the R and W terminals. If there is no 24 Vac, check if the circuit breaker has tripped and reset it if necessary. Also, check if the system fuse is blown and replace it if needed. Ensure the power switch on the HVAC equipment is in the On position. Inspect the wiring between the thermostat and HVAC equipment, replacing any broken wires and tightening loose connections. If 24 Vac is present, continue with further troubleshooting.

Why is the temperature display on my Trane XT500C Thermostat wrong?
- A
  Andrew FlemingAug 28, 2025
  If the temperature display on your Trane Thermostat is incorrect, it may be due to a few reasons. The room temperature display may have been reconfigured, so you should enter Installer Setup number 37 and reconfigure the display. Also, the thermostat may be configured for °F or °C display, so enter Installer Setup number 14 and reconfigure the display. Finally, the thermostat may be in a bad location, so relocate the thermostat.

Why is the outdoor temperature on my Trane XT500C Thermostat not working?
- C
  Carolyn MartinezAug 30, 2025
  If the outdoor temperature is not displayed or is incorrect on your Trane Thermostat, first check that the option is activated by entering Installer Setup number 24 and setting it to 1. Note that the thermostat must have OT terminals and a TAYSENS100A installed. Also, the outdoor sensor may be connected incorrectly, so refer to TAYSENS100A installation instructions and check wiring between the thermostat and sensor. Finally, you may have the wrong sensor, so replace the sensor with a TAYSENS100A sensor.

Why does my Trane XT500C turn on and off quickly?
- F
  Frederick WeaverSep 1, 2025
  If the heating or cooling comes on momentarily and then shuts off with your Trane Thermostat, it might be because the heat or cool circuit is opening up or becoming high impedance. To resolve this, add a resistor in parallel with the load or install an interface relay.

What to do if my Trane Thermostat shows the heat/cool indicator but there is no air?
- S
  Scott MoralesSep 4, 2025
  If the system on indicator (flame or snowflake) is lit on your Trane Thermostat, but no warm or cool air is coming from the registers, it might be because the heating/cooling equipment turns on the fan only when the setpoint is reached. Wait a minute after seeing the flame or snowflake before checking the registers.

Why is the LED lit on my Trane XT500C?
- J
  Joanna ReynoldsSep 6, 2025
  If the LED is lit on your Trane Thermostat, it could be because the system switch is set to Em. Heat. Try moving the switch to Heat or Auto. If that doesn't solve the problem, it could indicate a compressor failure, and you should contact a service technician.

What to do if the Trane XT500C indicator is on but there's no air coming out?
- J
  Julie HunterSep 8, 2025
  If the system on indicator (flame for heat, snowflake for cool) is displayed on your Trane Thermostat, but no warm or cool air is coming from the registers, it could be because the heating equipment turns on the fan only after the furnace has warmed up to a setpoint, so wait a minute after seeing the on indicator and then check the registers. Alternatively, the heating or cooling equipment may not be operating, so verify operation of heating or cooling equipment in self-test.
