If your air conditioner or furnace doesn’t seem to get the job done, it may not be the system itself causing the problem. You may have to wonder, “why is my thermostat not working?”

A malfunctioning thermostat is not just annoying. It can make your house unbearably hot or cold, and it will also raise your energy bills. If your thermostat isn’t working, here are a few reasons why. 

Dead batteries

It might just be this simple. Many thermostats run on AA or AAA batteries, and if they’re out of juice, then your thermostat won’t work. Though your thermostat won’t beep at you like a smoke detector, your temperature won’t read correctly, so your furnace may not kick on or off when it should.

Faulty power circuit 

If the problem isn’t batteries, your thermostat might not be working simply because it’s not getting power. A quick fix to your issues may be as easy as checking your circuit breaker to ensure your connection is still good. If the breakers have been tripped, flip them back on and see if that helps. 

Your thermostat is dirty

Practically everything runs better when clean, and your thermostat is no different. Day and night, it sits around and gathers dirt, dust, and other buildup that can break anything given enough time.

To clean your thermostat, you’ll first have to open it. This may be as easy as flipping it open, though you may have to get a screwdriver and open up the face. Once opened, gently brush the insides using a duster or even a paintbrush with soft bristles. If you’re careful, you can also give the thermostat a cleaning using condensed air. No matter which cleaning method you use, be sure to remove the batteries first before you clean it.

Your thermostat is analog

If you have an older analog thermostat, there are a few tricks you try to get it working again. Open it up, and you should see a metal coil or circle. Try giving this piece of metal a very gentle push in either direction and see if that gets things working. You may also need to review the user manual and check out the amperage setting. Follow the instructions on how to check the settings. This should only take a couple of minutes!

If your thermostat isn’t working

There are several reasons why your thermostat may not be working, and many of the issues are incredibly easy to solve. If your thermostat still isn’t working after trying these suggestions, it might be time to get a new thermostat. 

A smart thermostat may be the way to go. Not only will this solve your thermostat issue, but a smart thermostat can also reduce the cost of your heating and cooling.
