Why Does My Furnace Keep Blowing Fuses?

Apr 2, 2021 | Furnace, HVAC | 0 comments

If you’re a homeowner, then you might have had to deal with multiple blown fuses. While this is normal, you know there is a problem when it happens repeatedly. This is especially true for your furnace fuse! While most problems that result in your furnace blowing a fuse can be easily fixed, if left unchecked, small problems can quickly escalate into big expenses. That’s why we at Kettering-Oakwood Heating & Air put together a list of things that could cause your furnace to blow a fuse. If you recognize any of these problems, or if you’ve had to deal with your furnace repeatedly blowing a fuse, then it’s time to consult a professional!

  1. Dirty Parts

All HVAC systems are prone to the accumulation of dust over time. Because of this, it’s important to replace your furnace filter at least once a month. If dust builds up from your filter, then it can escape into the blower motor, causing the motor to malfunction and possibly overheat. This can cause the high limit switch to fail, which can result in a blown fuse. In essence, it’s important to keep your furnace filter and air vents maintained and clean!

  1. Bad Wiring 

Because furnaces cause vibrations that can loosen wires in the system, it is common for a loose wire to cause a short. So consider scheduling yearly or 6 month maintenance to ensure that everything is working properly. Additionally, wiring issues in your thermostat like loose or touching wires, can cause shortages. 

  1. Water Leaks

Water and electricity are never a good mix, so if you notice water leakage around your furnace unit, then you should address it right away. While they are usually an easy fix, unaddressed water leaks can cause a multitude of problems in the future, and they are a common reason for blown fuses.
