You check your thermostat to adjust the temperature in Creola, AL, only to find a blank screen. The switch is set to “On,” but pressing buttons does nothing. Fortunately, if you’re not experiencing wiring issues, a thermostat that’s blank for any of the following reasons is often easy to fix.
Dead Batteries
To start, if it uses batteries, replace them. Recall if your thermostat has been beeping or displaying warning signs. These can indicate that the batteries are about to die.
If possible, check the screen’s brightness. It might have dimmed automatically, making it harder to see.
Open Furnace Door
Some thermostats go blank when the furnace door is open. Make sure your furnace door is completely shut, and then check the screen again. Routine maintenance can help prevent issues like these.
Tripped Breaker
Your thermostat might turn off if you experience a power surge or accidentally overload the system. Try resetting the breaker or replacing your thermostat’s fuse. An overworked HVAC system can trip a circuit breaker, so make sure that your equipment is up-to-date and running smoothly.
Some HVAC systems have a float switch that turns off the power if the sensors detect high moisture levels. A professional could check your AC drain line for clogs.
Electrical Issues
Rodents, faulty installations, weather damage and even vibrations can cause loose connections or bad wiring, cutting the power to your thermostat. Never try to solve the problem yourself if you suspect this is the case. Instead, hire HVAC experts who can fix the issue or recommend an electrician.
Old Age
Sometimes, you just need a replacement. If the existing system is at least 10 years old, your thermostat might have given out. Research your model online to learn more about its lifespan.
