When your furnace runs nonstop in Opelika, AL, concerns about your heating bill inevitably come to mind. At the same time, you may also consider whether your system needs repairs. Let’s look at some reasons your furnace won’t stop running.
The Thermostat’s Temperature Setting
Your furnace runs until the indoor temperature reaches the temperature setting on the thermostat. A high-temperature setting requires it to run much longer, inflating energy bills. The HVAC system can’t reach the desired temperature when the thermostat setting is too high and the outdoor temperature plummets, so it runs constantly as a result.
The Fan Setting
The “on” fan setting on the thermostat instructs the fan to run nonstop, while the “auto” setting instructs it to run only when the furnace runs. The “auto” setting promotes energy efficiency and helps minimize drastic temperature changes.
Faulty Wiring or a Circuit Board Problem
Both damaged wiring and problems with the circuit board result in the furnace running nonstop. Other noticeable signs when the wiring or circuit board is bad include a burning smell, the inability to maintain a consistent indoor temperature and burners remaining on. Fixes include resetting the system, turning the breaker off and on and replacing the damaged wires professionally.
A Clogged or Dirty Filter
The filter in your furnace is responsible for capturing dust and dirt, so regular filter cleaning or replacement is an essential part of maintaining your system. You should also schedule an annual HVAC tune-up.
A dirty filter restricts air from flowing easily, so the furnace exerts more effort to heat your home. As a result, cool or barely heated air circulates throughout your home.
