Household thermostats typically use AA or AAA batteries. However, some models may require different battery types, so it’s important to check the manufacturer’s instructions or consult with a professional if you’re unsure. How do I safely remove the cover of a thermostat to replace its batteries?
Batteries have a lifespan of 5 years or more, while others may only survive three months. Even if your thermostat is permanently connected, it will most likely have a back-up battery that must be changed on a regular basis. This backup battery allows your system to continue functioning even if the electricity grid goes down.
Replace the batteries with the same type: LR6/AA 1.5V alkaline. Separate the Programmable room thermostat from its wall plate. Replace the spent batteries with new ones of the same type (AA), ensuring that they are installed in the correct orientation.
Gather any essential equipment, such as a flashlight and a flat-blade screwdriver , before getting started. Remove the outer cover from the thermostat housing. If you can't do it, push it up and pull it off the wall mount plate. Turn the thermostat cover over to see where you can insert new batteries.
It’s important to note that using the wrong type of battery can damage your thermostat or cause it to malfunction. Always make sure you use the correct size and voltage of battery as specified by your thermostat’s manufacturer.
Many thermostats still use batteries, while others draw power from your home’s electrical or HVAC system. It's a good idea to replace the thermostat battery on a set date every year. The start of autumn season is an excellent option. You should also replace the batteries in your carbon monoxide (CO) detectors.
