If your thermostat goes blank, it can be a sign of a few different issues. Here are some possible causes and solutions:
Power Loss: The most common reason for a blank thermostat display is a power loss. This can happen due to a tripped circuit breaker, a blown fuse, or a power outage. Check your circuit breaker or fuse box to make sure the thermostat is getting power.
Dead Batteries: If your thermostat runs on batteries, they may be dead. Check to see if the batteries need to be replaced.
Wiring Issues: If the wiring between the thermostat and the HVAC system is loose or damaged, it can cause the thermostat to go blank. Check the wiring to make sure it is properly connected and undamaged.
Thermostat Malfunction: If none of the above issues are the cause of the blank display, it may be due to a malfunctioning thermostat. In this case, you may need to replace the thermostat.
If you are unsure of how to troubleshoot or fix the issue, it's best to contact a licensed HVAC technician to diagnose and repair the problem.
