How To Fix Trane Thermostat Blank Screen?

In this guide, we’ve extracted the most truthful information for fixing the screen of your Trane thermostat.

Make sure that you follow our solutions consecutively to receive the best effects during the troubleshooting session.

Here’s how to fix the Trane thermostat’s blank screen:

Solution #1 Battery-Cycle Your Thermostat

There’s an easy way to fix the blank screen of your Trane thermostat. That is to perform a battery cycle on your unit by re-inserting the batteries of your device.

The batteries of your Trane thermostat can be exposed by removing the front panel of the device where you will see 3 batteries on the count.

Here’s how to battery cycle your Trane thermostat in easy instructions:

1. Eject the front panel of your Trane thermostat.
2. Expose the 3 batteries inside of your Trane thermostat.
3. Standby for 5 minutes until the power cycle is complete.
4. Re-insert the batteries back into your Trane thermostat.
5. Test.

Note: Make sure to keep the batteries out of your Trane thermostat for at least 5 minutes, in order for the current inside of your thermostat to be discharged.

Solution #2 Reconnect Thermostat Wires

You should reconnect the batteries of your Trane thermostat to determine if they are problematic and need replacing.

There are two general wires connected to your Trane unit and they can be exposed by removing the entire thermostat from the wall.

Here’s how to reconnect your thermostat’s wires:

1. Take out the front panel of your thermostat.
2. Undo the 2 screws that are holding the base of the thermostat onto the wall.
3. Slightly pull the base forward until only the 2 wires are holding the thermostat.
4. Unplug the wires from the respective slots and reconnect them.

Note: If any of the wires look damaged or cut somewhere across their body, you must replace them. 

Unfortunately, this process requires interacting with the entire HVAC system and you will have to contact a technician for the purpose.

Solution #3 Flip The HVAC Breaker

To fix the blank display of your thermostat, you should flip the breaker of your HVAC system.

That is located in a panel, somewhere across your house, and has a high chance of fixing the blank display on your Trane thermostat.

Here’s how to flip the breaker of your HVAC system:

1. Go over to the circuit breaker’s panel.
2. Locate the switch that is controlling the power of your HVAC system (should have a little HVAC label on the top).
3. Turn it down for 5 seconds and then flip it again slowly.

This will entirely refresh the power of your HVAC system, fixing any issues your Trane thermostat has developed.

Note: Keep in mind that resetting the power of the HVAC systems acts as a factory reset for your Trane thermostat. 

In that regard, you won’t be bothered with any additional steps to perform a separate reset on your device.

Solution #4 Replace Blown Fuses

In this solution, you should examine your HVAC setup for any blown fuses. A blown fuse may cause a variety of issues with your system, ACs, and the thermostat.

Here’s how to examine your HVAC setup for blown fuses and replace them:

1. Go over to your HVAC system setup room.
2. Open the HVAC furnace and expose the motherboard.
3. On the motherboard, there are little red or blue plugged components.
4. Check the head of the fuse is split-open.
5. Check the model of the blown fuse (written on the hardware).
6. Get a brand-new fuse of the same type and insert it into the slot you’ve taken the previous one off of.

Note: If you’re not confident to replace the fuse, contact an HVAC professional to help you with that. 

If you tend to change it, however, make sure to flip off the circuit breaker when interacting with the furnace’s hardware to avoid the potential danger of electric shocks.

How To Fix Trane Thermostat Blank Screen No Batteries?
