Time to Replace Thermostat Batteries? Some DIY TIpsYou’ll need to replace your thermostat batteries periodically to stay in control over the heating and cooling systems in your home. It’s not uncommon for homeowners to call for HVAC repair when they notice that display has gone blank in their thermostat, only to be told that all they need is to replace thermostat batteries.

Replacing the batteries of your thermostat is a simple and easy home maintenance task you can carry out yourself when necessary. As a rule, thermostat batteries will need to change about once every year. If you periodically change them, you shouldn’t have any problems maintaining control of your thermostat.

In addition to a blank thermostat screen, other signs that you need to change your thermostat batteries include a lack of response in heating and cooling equipment when you make thermostat adjustments and a low battery warning on your thermostat itself.

The Process of Changing Your Batteries

  1. When it comes time to change your thermostat batteries, you will first need to remove the housing off of your thermostat. The way you remove thermostat housing may vary with each thermostat. If you have trouble, try sliding the housing upwards to pull it off the mount plate.
  2. After you’ve removed the thermostat housing, you can turn the housing over to locate the battery slots. You may need to use a flat-blade screwdriver to help pry the original battery out of the thermostat housing.
  3. Slide the batteries into their slots. Check how the thermostat is marked to see if they should be inserted positive side up or negative side up.
  4. After you have put your batteries in place, you can replace the thermostat housing in its proper position over your wall plate. It should snap back into place when you have properly placed it back up on the wall.
