If the screen of your thermostat has gone blank and your heating and cooling system doesn’t seem to be working properly, it could be a simple case of needing to change the batteries. Many people don’t realize their thermostat even uses batteries until they encounter a problem with it not working properly. Some assume there is a bigger issue and call a technician to diagnose their system, wasting precious time and money on a problem that can easily be resolved. By changing your thermostat batteries once every year, you can prevent this from occurring.
It should be noted that not all thermostats use batteries. If you find that your thermostat has been working for a couple of years with no problems, then you probably have nothing to be worried about. Wall thermostats typically take AA, AAA, or 3V lithium batteries. Most battery-operated thermostats give some type of warning as the battery gets low – digital models can start to give this signal as early as two months before the batteries die. When this happens, you’ll see a blank screen on the thermostat and your heating and cooling system will cease to function properly. Fortunately, replacing thermostat batteries is a simple task anyone can do. Follow these simple steps:
1. Pull the thermostat housing off the mounting plate. If it is difficult to remove, try sliding it upward and then off.
2. Turn the housing over and locate the battery removal slots. Using a flat-head screwdriver, press into the slots and push the batteries out.
3. Insert new batteries into the slots.
4. Replace the thermostat housing back on the mount plate, aligning the pins on the back with the screw block. If necessary, slide the housing down and secure it in place.
