So your Trane thermostat screen has suddenly gone blank, and you’re not sure how to go about it? Keep reading!
In this post, I’ll 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, let’s head right into it!
Your Trane thermostat screen may go blank because the batteries are dead or the wiring is faulty. So, a quick way to fix this problem is to replace the batteries. If that doesn’t help, check your thermostat wiring.
If your Trane thermostat has no batteries, resetting the device may fix the blank screen problem.
That said, let’s go into more details on how to troubleshoot this problem.
Tips to Troubleshoot Trane Thermostat Blank Screen Issues
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 back 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.
