While many people give their heating and cooling equipment all the credit for providing a comfortable home environment, they should really be thanking their thermostat. As the brains behind the brawn, these technological marvels run the show, telling your HVAC system when to provide conditioned air, and at what temperature, but what happens if they can’t? Most programmable thermostats today rely on batteries to power the digital display, store preferred settings, and prevent your cooling or heating control system from turning off in the event of a power outage. Knowing how to replace thermostat batteries is the key to keeping your device in good, and continuous, working order; here’s how.
Timing Is Everything
Be proactive and aim to change the batteries in your thermostat, smoke and CO detectors each fall when you turn back the clocks. Signs you may need to change them before then include:
- A low battery warning
- A blank screen
- Unusual behavior from your HVAC equipment
*Note that if you are still experiencing any of these issues after battery replacement, call for service to have a professional diagnose the problem.
How to Replace Thermostat Batteries
- Remove the thermostat from the wall mount by grasping firmly and pulling toward you. If this fails, try sliding the device upwards before pulling.
- Flip the unit over and locate and remove the old batteries.
- Slide in the new batteries, making sure to line up the positive and negative ends correctly.
- Replace the thermostat back on the wall mount, by lining up the pins on the back with the terminal screw block, before sliding it down and snapping in to place.
