Furnaces shouldn’t overheat, so now that winter is upon Newtown, PA, you need to keep an eye on your furnace to make sure it stays in peak condition. Read on to learn about some things that can cause your furnace to overheat.
Poor Airflow
As with any HVAC appliance, proper airflow is essential for a problem-free operation. Several things can cause poor airflow, chief among them a dirty air filter. The overheating happens because the furnace has to work harder to reach the right temperature due to the dirt in the filter.
It’s also wise to make sure that all the vents in your home are open and clear of obstructions, particularly the intake vent where your furnace sucks in the air that it eventually heats and puts back into your home. Closing the vents only makes your furnace work harder.
Wiring Problems
Inside your furnace are a lot of electronics. Wires connect different parts of the furnace, including the blower motor and the limit switch. One or more wires can come loose and/or create a short circuit with the board that controls the furnace’s operation.
When that happens, the furnace could run until it overheats. Fixing such a wiring problem is a job for a pro.
Small Things Build Up Over Time
