How to Prevent Your Heating System From Blowing Its Fuse

Your heating equipment must be properly checked and maintained by certified technicians to ensure its reliability during the cold winter months. This is especially important if your heat pump or furnace often blows a fuse when in use, as a technician knows the best way to prevent further damage and costly repairs. Here heating and air conditioning repair specialist Stone Heating and Air shares some of the common causes behind your system blowing its fuse.

Fuse Replacement

Dirty, grimy air filters. Air filters that aren’t regularly cleaned or replaced will quickly collect dust and grime over time. This dust and dirt can slowly migrate to the blower motor and cause it to overheat more frequently. This can lead to burnout, causing the high limit to fail and break. To avoid this, make sure your HVAC system’s air filters are cleaned and replaced regularly. You can do this yourself, but it’s often better to have it done by a professional HVAC technician so that they can check for other potential problems that could lead to another blown fuse.


Faulty/loose wiring. Your heating equipment usually causes vibrations that will shake some of the internal wires. Sometimes, a wire will  slowly get loose and create a short, causing the fuse to blow. To ensure the wires stay tight, you’ll need to have them inspected by a trusted HVAC repair and replacement technician. They’ll know how to address the issue properly, as it can be dangerous to do it yourself. 


Water leaks. If you notice water occasionally leaking out of your heating equipment, it may be coming from an attached or nearby humidifier. The leak can also cause a blown fuse, so it needs to be addressed immediately, else it can damage your system over time. You’ll also likely need a trusted HVAC technician to do the job to prevent any future leaks.
