A blown furnace or heat pump fuse is the last thing anyone wants in the middle of winter. Other than infrequent maintenance, what are the usual culprits behind a blown fuse?
Allison Air Conditioning, your trusted heating and air conditioning service contractor, lists them here.
Dirt on sensitive furnace or heat pump components. Without routine maintenance, dirt and soot will accumulate on furnace or HVAC components. If grime reaches the blower motor, there’s a chance it will overheat and burn itself out. This will, in turn, break the electrical connection and cause the unit to fail.
Poor airflow and overvoltages. Dirty filters not only lower indoor air quality and impede airflow, but also increase the strain on the electrical system, forcing it to trip or blow a fuse to protect itself.
How often do you need to replace the HVAC filters? As a rule, HVAC or furnace filters should be replaced every three months. However, if you have pets or household members with allergies, you need to replace the filters at least once every two to three months.
Loose electrical wiring. Over time, the vibrations produced by the furnace can loosen the electrical wiring, blowing the fuse.
Malfunctioning components. Wear and tear will eventually take its toll on sensitive HVAC components, causing them to break down and blow the fuse.
Electrical shorts. If your heat pump’s fuse keeps blowing even after being replaced multiple times, a short in the electrical wiring might be to blame. As a rule, if your heat pump or furnace keeps experiencing the same issue over and over again, you should have an electrical technician or heating repair contractor inspect it.
How Often Should Your Furnace or Heat Pump Be Serviced?
It’s recommended that you schedule an inspection at least once a year, ideally in the spring or fall. Routine maintenance not only helps prevent breakdowns, but can also extend your furnace or heat pump’s lifespan.
