However, if resetting your Trane Thermostat doesn’t help resolve the problem, you want to try other troubleshooting steps. Keep reading to see other troubleshooting steps to try if your Trane Thermostat is not working properly.

How to Troubleshoot a Trane Thermostat?

If your Trane Thermostat is not working properly (reading incorrect temperature, not turning on AC, not heating, etc.), here are some troubleshooting steps to try:

1. Check the Batteries

If your Trane thermostat is malfunctioning (won’t turn on), the battery polarities may have reversed, or the batteries are dead.

To resolve this problem, remove the batteries from the thermostat and insert them back (following the correct battery polarity.

If this doesn’t help, the batteries might be dead. Get a fresh pair of alkaline batteries and replace the old ones. This should resolve the problem.

2. Flip the Circuit Breaker Off and On

Another troubleshooting tip to try if your Trane thermostat isn’t working is to flip your circuit breaker off and on. First off, check whether the circuit breaker has flipped off. If so, flip it to the ON position.

But if the circuit breaker is in the ON position, flip it off and back on.

You can locate your Trane’s thermostat circuit breaker in your breaker box. If your Trane thermostat doesn’t work after this, call a professional HVAC technician to inspect it.

3. Clean the Thermostat

If your Trane thermostat is reading incorrect temperature, dust/dirt could be the culprit. Remove the cover of your Trane thermostat and use a soft cloth to clean off dust or dirt.

More so, dirt/dust in your HVAC system could cause your Trane thermostat to read incorrect temperature. To fix this, try to replace the air filters in your HVAC system.

Your thermostat should work properly after this. But if not, continue to the next step.

4. Calibrate Your Trane Thermostat

Another way to fix incorrect temperature readings in your Trane thermostat is to calibrate the device.

To calibrate your Trane thermostat, get a thermometer and tape it to the wall close to the thermostat. Now, wait 15 minutes and check if the temperature readings are the same.

If the thermometer has different temperature readings, the problem might come from the thermostat display. Contact a trained HVAC technician to help you handle this.

5. Inspect the Wiring

Your Trane thermostat may also malfunction if the wires are loose or pinched. If you’re having issues with your Trane thermostat, such as not turning on, not cooling, and the like, check that all the wires are in order.

If you’re not sure how to check your Trane thermostat wiring, get an HVAC technician to inspect and fix any wiring issues in your Trane thermostat.

So that’s how to reset your Trane thermostat (even after a power outage).

As mentioned earlier, resetting your thermostat helps to fix some malfunctions in the device.

However, if the problem persists after resetting the thermostat, try other troubleshooting tips—such as changing the batteries, flipping your circuit breaker off and on, cleaning the thermostat and checking the wiring.

More so, if you’re having issues with changing temperature on your Trane thermostat, this could be happening because the device is locked.

If your Trane thermostat is still malfunctioning, contact an HVAC expert to run a check on the thermostat and HVAC system.
