It can be disconcerting when you notice that your smart thermostat screen is blank and your HVAC system isn’t turning on. This generally isn’t a reason to panic. Here are some possible reasons your smart thermostat screen in Los Banos, CA, is blank and what you can do about it:
Dead Batteries
Many smart thermostats use batteries to run. If your thermostat has batteries, you might see an indicator display on the screen showing low battery levels. Thermostats generally use AA or 3-volt lithium batteries that are easy to change.
Wiring Issues
If your thermostat is hard-wired, it’s entirely possible that the wiring is faulty when the screen goes blank. The wiring enables the thermostat to interface with the heating and air conditioning equipment. If you suspect that the wiring isn’t working or properly secured in place, contact an HVAC company so that an experienced service technician can properly address any electrical issues.
Tripped Safety Switch
An HVAC system has a built-in safety switch that trips to prevent it from overheating. When the switch trips, the HVAC system will shut off and the smart thermostat screen will go blank. A service technician can check the HVAC system to see if it needs repair or needs to be reset.
Open Furnace Door
A furnace door that’s ajar will signal your thermostat to turn off. Closing the door tightly should solve the problem, letting the thermostat turn back on.
Tripped Breaker
Thermostats connected to the main electrical system will go blank if their breaker flips off due to a power surge or blown fuse. This generally happens if the thermostat doesn’t have a battery backup. Resetting the breaker or replacing the fuse will fix the issue.
A blank smart thermostat screen may be alarming, but there are multiple steps you can take to fix the issue. If you aren’t able to get your thermostat to turn back on, contact the HVAC experts at CEN-CAL Air Heating and Cooling. We’ll repair the device promptly and restore its functionality.
