The when, where, and why of thermostat battery changing.


How to change the batteries in your thermostat is often times preceded by another question: how do I know when to change my thermostat’s batteries? Well, we can answer both of these questions. Let’s start with when to change your batteries. If you are a procrastinator, you could wait until your home becomes excessively hot or cold. This is an indicator that the batteries have died and your home is currently at the mercy of  Mother Nature. If you’re not inclined to allow your thermostat to die before you change the batteries, you could look for your thermostat to flash a battery symbol. Once this flashing starts, you have from 1 – 2 months of battery life left. Those who are proactive will probably want to change the batteries once a year, or once a heating/cooling season.

Now that you know when to change your batteries, it’s time to learn how to replace your thermostat’s batteries. The first step is to read the instruction manual for your model. After all, thermostats are not universal. Thus, what you need to do for one model may not be the same for another. For most, however, you’ll start by pulling the housing from the wall mount. If it doesn’t remove easily, try pushing the housing straight up to disconnect from the housing. Turn the housing over to find the battery slot. Remove the batteries with a flathead screwdriver. Replace the old batteries with the flat end going into the negative position, and the raised side into the positive position. Finally, you will put the cover back on the battery slot and put the housing back on the wall mount. Congratulations, the only thing you’ll need to do now is sit back, relax, and enjoy the comfort of perfect temperatures in your home.
