While you might know a tripped breaker or a blown fuse isn’ta giant deal, there are several situations where you might risk serious issues if you dont address what is causing your fuse to blow in the first location.
Some regular causes of why your furnace may be blowing fuses are disfigured wiring, dirty air filters, the thermostat metal frame, or worn or fault components, but poorly affixed and/or disfigured wires can cause your furnace to short circuit & blow a fuse.
If this is the case, it’s best to let a professional inspect the wiring & repair the problem. A lack of maintenance can lead to dust & debris accumulating on the air filters. If air filters aren’t regularly cleaned or substituted, grime may migrate to the blower motor. This causes it to overheat & lead to failure. Thermostats surrounded by metal frames have been known to cause furnaces to blow fuses. When the wiring inside the thermostat touches the metal frame, it creates voltage issues & can potentially blow the control board, a fuse can blow. Faulty or failing furnace parts such as a capacitor, blower motor, or transformer can cause the component to short circuit. If you suspect that you have any of these issues, do not hesitate to call an Heating & Air Conditioning professional so you can prevent unnecessary damage to your component & fancy repairs. Before you go looking for a up-to-date fuse, you should make sure you are actually dealing with a blown fuse & not some other issue. Checking your furnace fuse is a simple thing to do & doesn’t take much time. Still, contacting a professional to inspect your furnace may be the better cause of action if this isn’tthe first time you have had this concern with your furnace.
