Programmable thermostats help you save money on energy bills by allowing you to program your heating and cooling system so it uses less energy when you’re away from home. Most programmable thermostat models work efficiently and reliably, but they can still encounter problems. Knowing what to look for may help you resolve the problem, and there are a few common issues to investigate. These include:
- Dead batteries: If your thermostat batteries are more than six months old, replace them. Turn the thermostat to the “off” position and then remove the front cover of the thermostat unit. Remove the battery compartment cover to access the batteries and replace them with new ones.
- Blown fuse: Most thermostats have a filament inside that looks that what you’d find in a standard light bulb. When too much power goes through it, the filament separates and the fuse won’t function properly. Remove the fuse and replace it with a new one.
- Malfunctioning HVAC equipment: Sometimes thermostat issues are not caused by the thermostat itself. If your thermostat is set to cool, switch it to heating, or vice versa. If the opposite system turns on, then the problem is in your HVAC equipment, and not the thermostat. Contact a certified technician to inspect and service your system.
- Normal wear or damage: If none of these troubleshooting steps resolves the problems, your programmable thermostat may be at the end of its service life, or its internal components may be damaged. In this case, you should replace the thermostat.
