Are you facing some pesky thermostat problems and aren’t sure where to turn?
If so, then you’ve come to the right place. A broken thermostat can be a cause for alarm for any homeowner. After all, your family depends on it to stay warm in the winter and cool in the summer.
Fortunately, the solutions for most thermostat issues are simple and easy to apply yourself. To learn how to troubleshoot your thermostat, keep reading.
1. Blank Thermostat Display
Most types of thermostats sold today have digital displays or screens built in. If the display on your thermostat appears to be blank and won’t respond, it may not be getting power.
The solution for this should be simple. Either replace the batteries or, if it’s a hardwired thermostat, check the appropriate circuit breaker.
If neither of these steps solves the problem, make sure a safety switch on the HVAC system hasn’t been tripped that might have caused the entire system to shut down.
2. Thermostat Not Turning On
If your thermostat isn’t kicking in and telling the HVAC system to turn on, there are a number of possible causes.
First, double-check that the thermostat is set to the desired setting. If the system runs briefly and then shuts down again, it may be overheating. Try replacing the air filter and opening all of the vents to improve airflow.
3. Can’t Change the Thermostat’s Temperature
There might be a child lock setting on your thermostat that would prevent anyone from changing it if it’s on. Make sure the child lock isn’t activated on your thermostat.
If you’re using a non-display thermostat that isn’t working, it may not be getting power. Try replacing the batteries or checking the circuit breaker.
Finally, the wiring inside the thermostat might have gone back. Open it up and look for corroded, loose, or detached wires.
4. Thermostat Not Reaching the Set Temperature
Often, the reason a thermostat isn’t reaching the desired temperature is that it’s facing direct sunlight or in a room that’s warmer (or cooler) than the rest of the house. This can give it an inaccurate temperature reading.
Otherwise, the sensors are likely either dirty or damaged. You can clean the sensors by removing the back cover and cleaning all the parts inside with a soft-bristled brush.
5. System Running Continuously
Finally, if your system is running nonstop, make sure the fan isn’t set to the “always on” setting. It should be set to “auto,” which means it will turn on only when the heating or cooling system is working.
