Do You Know How to Replace the Batteries in Your Thermostat?

There are many possible causes when your air conditioning system fails to function as it should. The problems is often determined by a process of elimination, and can range from a minor do-it-yourself fix, to a more technical problem for which you will need the help of a professional. One of the minor problems could be as simple as needing to replace the batteries in the thermostat. In order to ensure proper functionality at all times, it is important to know when and how to replace the batteries in your thermostat.

When Replacement Is Needed

Depending on the type of digital thermostat you own, it may use AA alkaline batteries, AA alkaline, or 3-volt lithium batteries. Regardless of what kind of batteries they contain, these advanced devices have a low battery indicator that will alert you when replacement is necessary. In some cases, however, you may experience unusual behavior from your heating or cooling system when the batteries need replacement. But even if you are not given an alert and the system is running fine, you should plan on switching out the batteries once a year.

How to Replace the Batteries in Your Thermostat

Replacing the thermostat batteries really is one of the least intimidating of the do-it-yourself AC tasks. Just follow these steps:

  1. Remove the thermostat housing from its mount plate by sliding it up, or snapping it off the wall mount.
  2. Turn the unit over and locate the battery compartment.
  3. Extract the batteries. Many units have a ribbon to pull on that will pop them right out. If not, use a flat-head screwdriver to pry them out.
  4. Align the batteries correctly as indicated.
  5. Line up the thermostat with the wall mount and slide it back into place.
  6. Test the thermostat to make sure it is in good working order. If it does not seem to be working properly, then a low battery may not have been the issue and a technician should be called.
