Today's home furnaces are complicated appliances with intricate electrical systems for higher efficiency and comfort. Different components can develop faults, from the main electrical control panel to the heat exchanger to the thermostat. A furnace repair professional will have the knowledge to troubleshoot and fix various faults. What are some of the common faults that develop in a furnace's electrical system?

1. Fluctuating Main Power 

The furnace's power supply is connected to the home's electrical system. If the voltage from the mains fluctuates, it can cause the electrical system to misfire or even shut down. The main electrical panel could also be faulty. 

If you have no power backup like a generator or solar power, you are vulnerable to heating failures during power outages. You can ask the furnace maintenance professional to recommend an appropriate power backup source. 

2. Faulty Thermostat    

The thermostat is a simple device that switches the furnace on and off depending on temperature settings. It comprises a sensor that reads room temperature and a switch that alerts the furnace to turn on when required and off.

Today's thermostats are programmable and can also learn the home's heating demands, so they adjust automatically. However, a thermostat that goes out of calibration knocks off the heating system; it does not ignite when required and won't shut when desired temperatures are reached. A furnace repair technician will test for correct thermostat calibration and recalibrate if necessary. 

3. Faulty Furnace Transformer   

A transformer converts mains electricity into 220 volts for the furnace's control panel. A surge can blow it, and it also degrades from overheating. The best remedy for a faulty transformer is a replacement to avoid serious power surges and electrical fires. 

4. Loose and Shorted Wires    

Loose, damaged, or crossed wires can also cause problems in the electrical system. Exposed wires can cause electrical shorts and shocks. In addition, they are fire hazards. You need an overhaul of the wiring system if the wires are degraded.

5. Damaged Blower Motor   

A blower motor is a fan that pushes air through the heating ducts in the home to distribute heat evenly throughout the house. It is one of the most common things for a furnace to break down. You will notice there is no heat coming from the registers even when the furnace is on. Call a furnace repair technician to fix it. 

If any of these components develop electrical faults, it can cause heat loss and poses a fire and electricity hazard. If you suspect an electrical fault, call a professional furnace repair service provider in your area to diagnose and remedy it.
