24/7 Emergency Service

For the enormous benefits that programmable thermostats provide, they rarely malfunction or have problems. One fairly common problem is a blank screen, however, which worries homeowners, but can often be the result of dead batteries.

Most thermostats that use batteries have a low-battery warning that will let you know when it’s time to find a new set of batteries. Changing the batteries is a simple job, so try that before you call in an expert. Before you get started on this simple task, get the appropriate batteries (usually AA or AAA). You also might want a small flathead screwdriver to pry the batteries out. Here’s a quick guide on how to replace thermostat batteries.

How to Replace Thermostat Batteries

  • Remove the thermostat. Most models can be simply clipped off, or slid up and off the wall housing. Be gentle to ensure you don’t damage the unit. If your thermostat is hardwired to your home’s HVAC system or electrical system, you can tell because of the connecting wires that won’t let you remove the thermostat.
  • Find the battery slot. The most common location for batteries is in a slot on the back of the thermostat. Once you locate it, take the batteries out, but pay attention to the orientation of the batteries.
  • Put the new batteries in. Now that you know which way the batteries should face, put the fresh ones in. If you forgot to look at the orientation, look on the thermostat for markings that will guide you.
  • Remount the thermostat. Now that your unit has fresh batteries, put it back on the wall housing and see if it has power. If it doesn’t, there could be a problem that needs professional attention.
