If you’re like most people, you probably don’t spend much time or energy thinking about your thermostat. However, that doesn’t make it any less essential when it comes to regulating the environment in your home.

Your thermostat is the control center of your entire HVAC system. If it suddenly stops working or otherwise goes on the fritz, then you’re effectively stuck without the ability to control your furnace and air conditioner until it’s fixed.

Having a reliable go-to HVAC company that can address issues as they arise or perform routine maintenance is naturally a must. However, it’s also worth knowing how to troubleshoot your thermostat yourself in a pinch. Here are some suggestions to try.

Switch Out the Batteries

The most common reason a thermostat might suddenly stop working is also one of the easiest to fix, especially if it doesn’t appear to be getting any power at all. When was the last time you checked or changed the batteries?

If it’s been a while, try swapping the current batteries for a fresh set. That could be all it takes to get your thermostat to power back up.

Reset the Thermostat

Most electronics and digital devices occasionally require a reset to get back to working the way they should if they’re having problems, and thermostats are no exception. This may especially be the case after events like blackouts or brownouts, as sudden shutdowns can easily confuse systems and stop them from communicating properly when power returns.

Each thermostat is different as far as how to perform a reset, so consult your owner’s manual if there’s any doubt as to the procedure for yours. Possibilities include the pressing of a recessed button, 30-second shutoffs, or temporary battery position adjustments.

Rid Your Thermostat of Dust and Debris

Dirt and debris can definitely affect the inner workings of a thermostat’s electronics, especially if it’s been a while since you last cleaned yours. The wiring needs to be able to connect with the appropriate terminals to function properly, and accumulated dust can easily get in the way.

Refer to your owner’s manual for directions on how to remove the thermostat’s cover. Then, use a vacuum hose to remove as much of any dirt inside as possible. If you notice any caked-on dirt, try gently cleaning it with a soft, clean cloth or cleaning brush. If you see any corrosion, try addressing it with some contact cleaner made especially for electronics.

Consider Other Power Issues

If simpler solutions like the above don’t get your thermostat back up and running again, it’s time to look into other possible reasons for an electrical interruption. Start by checking your circuit breaker box for tripped breakers. Switch any you find off and then back on to restore power.

You may also want to check your furnace switch. If it’s not powered on properly, it will absolutely affect the function of your thermostat.

Check the Thermostat’s Programming

If you have a programmable thermostat, then you don’t need to be told how well it simplifies the process of maintaining optimal temperatures in your home. But sometimes, even the most user-friendly options need a little troubleshooting in the programming department. You may find displays don’t accurately reflect the true temperature in a room, etc.

If this is a possibility, try cleaning the thermostat, as well as checking the filters in your HVAC system and replacing them if necessary. You should also check your owner’s manual for instructions on resetting or correcting faulty programming.

If none of the above suggestions fix your thermostat issues, it’s best to have a professional look at your system and get it up and running again for you.
