In this post, we explain the reasons behind this issue and what you can do to get your Trane thermostat up and running.
If that sounds like what you’re looking for, then let’s head right into it.
Why is my Trane Thermostat Blank?
For the most part, your Trane thermostat screen may go blank because the batteries are dead or the wiring is faulty.
With that in mind, let’s explore some troubleshooting tips to help fix your thermostat.
Trane Thermostat Blank Screen: Try These Troubleshooting Tips
1. Replace the Batteries
As mentioned earlier, one of the likely causes of blank screen issues in your Trane thermostat is low/dead batteries.
If your Trane thermostat has been working properly, but suddenly goes blank, chances are the batteries are dead.
To fix this problem, get a new pair of batteries and replace the old ones. Ensure you use the recommended batteries (non-rechargeable alkaline batteries) and do not mix new batteries with old ones.
More so, ensure the new batteries are installed correctly following the battery polarity (+/-).
If your Trane thermostat screen is still blank after replacing the batteries, continue to the next step.
2. Power Cycle Your Thermostat
Issues with your home’s main power source can also cause your Trane thermostat screen to go blank.
If the issue persists after replacing the batteries, try power cycling your thermostat via the circuit breaker.
Here’s how to do this:
- Ensure your HVAC system is turned off.
- Go to your home’s circuit breaker panel. Next, find the switch for your thermostat in the breaker box.
- Turn the switch off. Then wait for about 30 seconds and turn it back on. This will power cycle your thermostat and possibly fix the blank screen issues.
Note: If you meet the switch in the off position, it means the circuit breaker tripped—probably because of a power surge. Flip it on, and then check your thermostat to see if the problem is resolved.
If this doesn’t help, continue to the next step.
3. Inspect Your Thermostat’s Wiring
Your thermostat’s wiring can also cause this issue. If any of the wires are loose, pinched, or burned, the thermostat may go blank.
If your Trane thermostat screen is still blank after replacing batteries and power cycling it, check to see if the wiring is faulty. Ensure you insert loose wires into the right terminals and replace any burned wires.
Note that wiring issues are best left for professionals to handle. If you have no experience handling wiring issues in a thermostat, get a licensed professional to check and fix your thermostat.
How do you reset a Trane thermostat?
You can reset your Trane thermostat through the circuit breaker.
Find the switch for the thermostat in your breaker box, then switch it off for about 30 seconds and switch it back on. This will reboot/reset the thermostat.
How do you troubleshoot a Trane thermostat?
If you have issues with your Trane thermostat, you can start your troubleshooting by replacing the batteries. Next, reset the thermostat and check the wiring. If everything fails, get an HVAC expert to examine and recommend troubleshooting steps.
Do Trane thermostats have batteries?
