A thermostat is integral to home comfort, as you use this device to set your desired temperature targets. When you see a blank screen, you feel frustrated because you cannot interface with the HVAC system in your Miles, TX home. Some causes only require minor repairs, while others demand professional attention.
Dead Batteries or Tripped Breaker
There are many reasons that your thermostat screen will be blank. A common one is that the batteries may be dead, if your thermostat uses batteries. You may also have a tripped breaker.
Loose Wiring
A blank screen can also be the cause of loose wiring. Over time, wires can loosen because of wear and tear.
Blown HVAC Fuse
Some HVAC systems have internal fuses that can go bad. If your system has a fuse, your thermostat can go blank if the fuse goes bad.
Old Thermostat
Sometimes, thermostats are at the end of their lifespans. As they age, they can malfunction, which can also cause your screen to go blank.
There are some quick troubleshooting steps to follow to get your thermostat working again. You can start by changing the batteries to see if that restores functionality. If that does not work, you can check your breaker box to see if you have a tripped breaker.
Once you confirm your breaker is not the problem, check the power switch to your HVAC system. Turn the power on if it’s in the off position.
