Innovation and technological advances have revolutionized many household tools, appliances, and devices. The HVAC system thermostat is no exception. As the brain behind your heating and cooling system, your thermostat is the director of the show, calling for air based on your desired temperature setting. Advanced smart thermostats today not only control your HVAC system but can also lock doors, control lights, and operate other systems. Additionally, homeowners can control Wi-Fi and Bluetooth-connected thermostats from their smartphones and other devices. Among the many options for smart thermostats on the market today, Trane offers quality devices with advanced features and reliable performance.

Even with the technology and innovation that goes into many Trane thermostats, they are still subject to glitches and minor malfunctions. Fortunately, many of the issues you might encounter with your thermostat are easily resolved. If you have a problem with your Trane thermostat touch screen not working, there are a few things that you can do to troubleshoot the issue.

Battery Replacement


Depending on your model, your thermostat touch screen might be battery-powered. If this is the case, the problem could be as simple as dead batteries. Typically, your thermostat will display a low battery warning; however, it can go unnoticed. To check the batteries in your device, you’ll want to follow the instructions in your owner’s manual for removing the face cover and accessing the batteries. In general, it is a good idea to replace your batteries on a routine schedule to avoid any issues. You might consider putting your thermostat on the same schedule as your smoke detectors and installing quality batteries simultaneously.

Dirty Housing

In some instances, the problem with your thermostat touch screen could be the result of dust and other particles. Over time, your system might collect airborne particles such as dust. If this buildup occurs inside of your thermostat, it could interfere with the operation of your touchscreen device. You can gently clear the debris away using canned air to remedy this problem. This will help clean your device and restore functionality. In general, it is a good idea to clean your touchscreen thermostat regularly. Keeping up with this could help avoid a malfunction.

Locked Thermostat

Your display may still be functional in some cases, but you can’t change the temperature. If this is the case, it could be that your thermostat is locked. To unlock your Trane thermostat, press the plus and minus buttons simultaneously for three or four seconds. This will unlock the device and allow you to adjust the temperature. If this doesn’t work, you can try resetting the thermostat using the reset button. If this fails to remedy the issue, you may have a display issue and require the assistance of an HVAC professional.

Power Issues


Power issues outside of problems with dead batteries could also cause problems with your touch screen. A blown fuse could cause your thermostat to malfunction. Checking and changing the fuse could restore functionality to your touch screen. Additionally, if the circuit breaker in your house has been tripped, the power to your thermostat could be interrupted. A tripped float switch will also cause a screen issue and can be resolved by resetting your circuit breaker. Other electrical problems from poor wiring due to installation issues could also create an issue. You may need to contact a qualified HVAC technician to help address any wiring problems.

Whenever you troubleshoot your touchscreen thermostat and try to find an issue, it is important to make sure that you cut the power to the device. Additionally, you might also need to check that the filters and hoses in your unit are clean and working, as these could also cause thermostat issues. If you cannot determine the issue with your thermostat, you will need to contact an HVAC technician to help diagnose and correct the problem.
