When was the last time you changed your programmable thermostat’s battery? If it’s been a while or if you can’t remember, chances are it’s time to have them changed. You should replace batteries in a thermostat whenever you see the "low battery" icon appear on its screen. Otherwise it could stop functioning when you need it most.
Many of our clients simply replace the thermostat batteries at the same time they replace the fire detector and/or CO monitors each year- often at the same time they change their clock setting either in the fall or spring. Alternately, they sign up for a reminder service with us and get an email once a year to remind them.
If you want to know how to replace batteries in a thermostat, simply follow the steps below:
- Remove the thermostat from its wall mount, usually by sliding it upward and pulling it away from the mount, but don't force it!
- Turn the unit over and locate the battery slot. You may have to use a flat-head screwdriver to remove the door covering the slot.
- Memorize the orientation of the old batteries. You want to make sure fresh batteries are installed the same way. Most thermostats feature markings showing how the batteries should be positioned.
- Replace the old batteries with a new set. Don’t forget to reinstall the battery slot cover.
- Mount the thermostat back on its wall mount securely. You may have to re-enter your settings before you’re ready to use the thermostat again.
There’s a good chance that the battery changing procedure may be different from what you see here. In that case, it’s a good idea to consult the manufacturer’s user manual for more details. If you’ve replaced the batteries and the thermostat still doesn’t work, you may need to call an HVAC technician for further assistance.
