Top 8 Reasons Why Your Thermostat Went Blank
If your thermostat screen is blank, it could be due to any of the following reasons:
1. The batteries are dead.
This is the most common reason for a blank thermostat screen. If your thermostat uses batteries, check to see if they need to be replaced.
2. The power is out.
If your home has lost power, your thermostat will also go off. Check your circuit breaker to see if the power is out in your home.
3. The fuse is blown.
Another reason for a loss of power to your thermostat could be a blown fuse. Check the fuse box in your home and replace any blown fuses.
4. There’s a tripped GFCI outlet.
If your thermostat is plugged into a GFCI outlet, it could be the reason why it’s not working. Try resetting the GFCI outlet and see if that fixes the problem.
5. The thermostat is turned off.
It sounds obvious, but sometimes people forget to turn their thermostats on! Check to make sure that your thermostat is in the “on” position.
6. The furnace is turned off.
If your furnace is turned off, your thermostat will also go blank. Make sure that your furnace is set to “auto” so that it will turn on when the temperature drops.
7. There’s a problem with the wiring.
If you’re having trouble with your thermostat, it could be due to a problem with the wiring. Check the wiring and make sure that everything is connected properly.
8. The thermostat is set to “heat” mode.
If your thermostat is set to “heat” mode, it will only turn on when the temperature drops below the set point. Make sure that your thermostat is set to “auto” so that it will turn on and off as needed. Thanks for reading! We hope this article was helpful.
