Is Your Furnace Acting Up? Check Your Thermostat

Guy checking the furnace

Aging or malfunctioning wiring, extreme changes in temperature, dust buildup, and many other issues could sometimes lead to the furnace’s thermostat to malfunction. Thermostat issues make your unit incapable of regulating your home’s temperature. These could likewise result in your furnace delivering inconsistent amounts of heat, short cycling, or halting heat production entirely.

Below are some of the most common issues you need to watch out for:

Basic Power Issues

If your wireless thermostat isn’t working, check the batteries first. If the batteries are fine, see if the switch is turned on. Otherwise, check if you’re having issues with your circuit breaker or fuse.

Faulty Wiring

Aging, damaged, loose, and broken wiring could result in your thermostat losing connection with your HVAC. It’s a great idea to get your thermostat inspected for wonky wiring and related issues if you’re experiencing problems with your furnace, suggests Whipple Service Champions and other furnace repair expert in Salt Lake City.

Debris and Dust Buildup

Cleaning a thermostat is pretty straightforward. Set it first at the lowest setting, remove the cover, and clean the bimetallic coil with compressed air or a soft-bristled brush. Next, set the thermostat to the highest setting and do a second cleaning of the bimetallic foil.

Incompatible Parts

Your thermostat should match your HVAC system according to type, furnace capacity, and capability. Otherwise, mismatched parts could result in miscommunication and lead to system failure.

Heat Anticipator Problems

This component communicates to your thermostat when it should shut off the burners of the furnace. A malfunctioning heat anticipator could cause your furnace to short cycle than necessary. Consult an HVAC repair technician to see if your heat anticipator needs a repair or adjustment.

Incorrect Temperature Reading

This could be the cause if your furnace suddenly turns on or off, or doesn’t turn on when it should. Where is your thermostat positioned in your home? Ideally, it should be positioned away from windows, doors, drafty spaces, direct sunlight, and heat sources like radiant heaters and fireplaces.

When you’re having issues with your HVAC system, it’s not necessarily the system itself that’s malfunctioning. It could be due to different things, such as a malfunctioning thermostat. Check your thermostat first to rule it out and if it’s not, get a professional technician to inspect your HVAC.
