Why Is My Thermostat Screen Blank in Glendale, CA?

Programmable and smart thermostat screens display important information that lets you know your system’s status, including the current temperature and mode your HVAC system and its fans are in. Therefore, if the screen suddenly goes blank, it can be distressing. Here are a few reasons why homeowners in Glendale, CA might suddenly see blank thermostat screens.

Dead Batteries

The simplest explanation for why your thermostat’s screen has gone blank is that the thermostat’s batteries have died. In this situation, you can simply remove the old batteries and replace them with new ones.

Wiring Issues

Wiring problems can also happen to your thermostat, though you should not attempt to fix them on your own. Be sure to schedule an appointment with a licensed HVAC technician instead.

If your thermostat does have a wiring issue, then one possibility is that some wires have come loose or moved out of place, thus breaking the electrical connection to the device. Alternatively, the wires may have tears, fraying or other damage that renders them unable to transmit electrical current. An HVAC technician can fix loose wiring with a simple maintenance check, but the latter will likely require more work.

Tripped Circuit Breaker or Other Safety Switch

Another possibility is that your HVAC system may have somehow tripped your circuit breaker, thereby cutting off power to your entire system, including the thermostat. This may happen because your HVAC system is too large and powerful for your home, or it may be that your circuit breaker is itself old and dysfunctional.
