Thermostat Not Working? Time To Troubleshoot

Your thermostat regulates the temperature in your home. If you notice your HVAC system's starting and stopping at random times, you may have a faulty thermostat.

Why Is My Thermostat Not Working?

From old batteries to tripped circuit breakers, there are a number of potential reasons for why your thermostat isn’t working.

If your thermostat is displaying inaccurate temperature readings or your AC and furnace systems are operating inconsistently, it’s likely your thermostat is faulty.

How to check for a faulty thermostat

  • Thermostats determine the temperature within the area of the thermostat itself. Even if your thermostat is working properly, it may be fooled if the thermostat is in a bad location, such as a near a window, vent, ceiling fan, or in direct sunlight. If one of these factors is affecting your thermostat's ability to read the temperature, it will turn your heating and cooling systems on or off at inappropriate times.

  • If one area of your home is much warmer or cooler than the rest of your house, check the thermostat to see if someone accidentally shut it off or turned it down. In that case, you will simply need to revert those settings to the temperature settings you'd prefer.

  • Try changing some of the settings on your thermostat. Is it responding to input from the buttons or touch screen? If it's on but not responding, it's likely faulty. If the screen is completely blank, the thermostat may be out of batteries.

If your thermostat isn't the issue, inspect other reasons for why your AC to keep turning on and off, or your furance. Consider other issues.

What to Do If Your Thermostat Isn’t Working?

A faulty thermostat can affect the operation and efficiency of your HVAC systems, so you’ll want to fix it right away to save your units from any damage. If you’ve reset breakers and cleaned the inside of your thermostat and it’s still not working, there may be a larger issue at hand.
