Programmable thermostats usually are quite durable, but they aren’t infallible. The good news is that troubleshooting a programmable thermostat isn’t difficult once you know which steps to take. And here they are:
- Check the device’s batteries (if it’s powered by batteries, rather than your home’s electrical grid) – The first thing you should do when your HVAC system stops operating is check your programmable thermostat’s battery power, along with the circuit breaker for the A/C, heat pump or furnace. Most thermostats will give you an alert when the batteries are low, but it never hurts to make sure.
- Take a look at the fuse – The next thing to check is the thermostat’s fuse. It isn’t uncommon for the fuse’s filament to become damaged. If this is the case, fixing it is quick and easy. Simply take the fuse to your local hardware store and ask for a replacement. Turn off the power to the thermostat before working with any wiring.
- Check heating and cooling system – If only one of your systems – the cooling or heating equipment – isn’t operating properly, your home’s thermostat probably isn’t the culprit. So once you realize that one system is not working, switch to the other system and check that one, too. If neither is operating, your problem may be the thermostat.
- Replace the thermostat – If your thermostat is relatively new, first check to see if there have been any recalls on that particular model. If the answer is yes, you can get a free replacement. The same is true if your device is still under warranty. Even without a recall or warranty, though, the situation isn’t catastrophic since replacing a thermostat, even a high-tech programmable model, isn’t going to break your budget.
- Install your new thermostat – For all but the highest-tech thermostats, you probably can install a programmable thermostat yourself. However, it’s important to follow the manufacturer’s installation instructions in order to ensure proper operation. If not, your home’s energy efficiency could be negatively affected. Once installation is complete, check both your heating and cooling units. If they still aren’t working, it’s time to call an HVAC professional because the thermostat wasn’t the problem.
