Like any other device, your thermostat may sometimes malfunction. But since it is the control center of your entire home comfort system in Montgomery, AL, it can be frustrating to see its display disappear. Here are a few reasons why the screen on your thermostat might go blank.
Dead Batteries
If your thermostat goes blank, before anything else, you should check its batteries. While not all thermostats use batteries, some that are direct connected do have backup batteries. The simplest explanation for what’s wrong is that the batteries have simply run out of power. Try replacing the batteries with new ones and see whether the problem corrects itself.
Electrical Issues
If, rather than running on batteries, your thermostat has a direct electrical connection to your HVAC system, then something may be wrong with the wiring that brokers that connection. Wires may be old, frayed, excessively bent, torn or chewed through by animals, for example.
Alternatively, it may be that your HVAC system is tripping your circuit breaker, causing the latter device to cut off power to every part of your home comfort system, including your thermostat. This may happen if your HVAC system is too large for your home or if some kind of malfunction is causing it to consume unusually high amounts of power.
Finally, one of your HVAC system’s safety switches may have activated and shut off the flow of power to your thermostat. In this case, there is some sort of underlying mechanical issue that is causing the problem and putting you at risk. HVAC technicians should investigate and resolve such things when performing either periodic maintenance or special repairs.
Age
Lastly, your thermostat may simply be so old that its components can no longer function properly. If your thermostat has been around for more than 10-15 years and none of the above possibilities can account for what’s going on, then this may be the explanation. If so, the solution is obvious: Replace your thermostat.
