A smart thermostat should display a lot of information on its screen that keys you into the state of your HVAC system and the climate conditions in your home in Lake Worth, FL. However, things may go wrong and the screen will go blank. Here are a few reasons you might have a blank smart thermostat screen:
Dead Batteries
Some smart thermostats have a common wire to draw electrical power from your home’s electrical system. However, others only run on batteries. Batteries can sometimes leak or run out of juice and die, and that’s the simplest explanation for why your smart thermostat’s screen has gone blank.
Tripped Breaker or Safety Switch
HVAC systems work with various safety switches and appliances. Their purpose is to prevent overloads to minimize damage to the system and keep you safe. Perhaps the most important of these is the circuit breaker, which is a device that cuts off the flow of electricity to the devices in your home when there’s a risk of a power surge. If you have a wireless thermostat keyed into your home’s electrical system and your HVAC system trips the breaker for any reason, the thermostat will shut off and go blank.
Some other safety switches include the high limit switch, which shuts off your furnace when it’s at risk of overheating, and the float switch, which can turn off your air conditioner when there’s too much moisture. Since tripping these switches will turn off your HVAC system, it can also turn off your thermostat. Resolving the underlying issues that activate these switches will usually require scheduling professional HVAC repair or maintenance services.
Wiring Problems
Lastly, your thermostat may have faulty wiring. Wires may have gone loose, frayed or sustained other kinds of damage.
