Here’s How You Troubleshoot a Programmable Thermostat

Programmable thermostats are an inexpensive way to save money and increase the comfort of your home. However, like any other technology, sometimes they will stop working correctly. Instead of buying a new one, try to troubleshoot your programmable thermostat with these basic steps:

  1. If your thermostat runs on batteries, check that they are not dead. The small cost of putting in fresh Here's How You Troubleshoot a Programmable Thermostatbatteries is worth it if it fixes your problem. Before you change the batteries of your thermostat, always set it to the “off” setting.

  2. Check the installation. Double-check that the temperature settings are correct and the thermostat isn’t turned off. Take off the cover and check to see if all wires are connected as intended.

  3. Identify the fuse of your thermostat. If the filament contained inside the fuse of your wired thermostat is separated because of a power surge, it will disable the device. You can find a replacement fuse at most hardware stores.

  4. Rule out your HVAC system. If your A/C won’t come on, check to see if your furnace will turn on. If it does, the problem isn’t with your thermostat; it’s with the A/C. Call in a technician to get your system fixed.

  5. Replace the thermostat. If nothing else has worked, it may be time to replace your programmable thermostat. Most problems will be fixed when you put in the new one, but if it still won’t work, you’ll have to call in a professional. Before buying a new thermostat, check to see if you have warranty coverage on your old one.
