The thermostat is the HVAC system's command center. If your home has heating and cooling problems, a malfunctioning thermostat is a likely culprit. Fortunately, most thermostat problems aren't major, so you'll probably just need to adjust your existing one rather than getting a new one. Here are the possible reasons behind your device getting off schedule, along with the steps you should take before calling a professional.
Thermostat Not Turned On
It may sound silly, but the first thing you should do is check whether your thermostat is on. Many homeowners get frustrated with their thermostat's improper functioning only to realize that it was turned off. Once you verify that your thermostat is on, make sure it's set higher than the current room temperature for heating purposes. For cooling purposes, set it lower than the room temperature.
Dirt
Dirt, dust, and nicotine buildup can interfere with both the electrical and mechanical components of the thermostat. Opening the cover and giving the components a good dusting should resolve the problem. Use a soft brush or compressed can of air.
Lack of Power
Your thermostat may not be getting any power due to a tripped circuit breaker, dead batteries, or a blown fuse. Take these steps to try and rectify the issue:
- Go to the breaker panel and find the breaker that your thermostat is on. Ensure it's in the "on" position.
- Take off the thermostat's cover and check the fuse. Replace the fuse if the filament inside it is broken.
- Change the batteries. Consult the thermostat's manual if you can't locate the batteries.
Wrong Location
Your thermostat won't read your home's average temperature correctly if it's placed poorly. Thermostats located near doorways, stairwells, drafty windows, kitchens, direct sunlight, and heat sources may continually send incorrect commands to your air conditioner or furnace. You'll need to contact a professional to have your thermostat moved.
