If you suspect a furnace electrical problem, your first step should be to call in an HVAC repair professional.
With the cold winter nearly upon us, you’ll want to check that your furnace will be able to keep you warm during those freezing nights safely. If you notice that your furnace isn’t working as it’s supposed to, it could be having an electrical system issue, or the HVAC system might be faulty.
Today, we’ll be looking at some of the top causes of furnace electrical problems. If you suspect a furnace electrical problem, your first step should be to call in an HVAC repair professional. The technician should be able to troubleshoot and fix your furnace in no time.
8 Common Causes
- Clogged Air Filter – Your furnace’s air filter should be changed regularly to avoid the buildup of dust and debris. If you haven’t changed it in a while, the chances are that it will be clogged. These will eventually get into the blower motor and cause it to overheat and burn the fuse. A clogged air filter is a fire hazard. Be sure to contact an HVAC technician to replace your filter and clean out your furnace.
- Contact with Water – Look out for water leakages around and from your furnace. Water contact will cause a short in the electric circuit. Get your HVAC technician to check any leakages from your furnace.
- Loose Wiring – Vibrations, when the furnace is running, can cause some wiring to come loose. Loose wires eventually cause electrical shorts. A loose wire can be pretty tricky to locate. An HVAC repair professional can help identify and fix loose wires and get your furnace up and running again.
- Dirty Fuse – Over time, the fuse in your furnace gathers dust and grime. The layers of dirt break the electrical circuit and cause shortages in the furnace. Get an HVAC technician to clean or replace your fuse regularly.
- Faulty Starter Capacitor – If your furnace’s starter capacitor fails, you’ll get electrical problems now and then. Hire an HVAC repair guy to change your capacitor at a relatively low cost.
- Faulty Transformer – Your home’s transformer can cause furnace electrical problems. Most electrical systems support 120 volts. Your furnace will require a transformer to convert the energy into the voltage needed to run it. If your transformer is faulty, your furnace might fail to ignite. You’ll need a professional to replace it.
- Bad Blower Motor – A faulty blower motor can cause your furnace’s fuse to blow. This is as a result of the motor drawing an excessive amount of power all at once. Replacing the blower motor will fix this problem.
- Faulty Thermostat – A faulty thermostat can cause Your furnace to work harder than it should, and this can cause internal wear and tear, leading to short circuits.
