Troubleshooting the Top 5 Common Problems of an Electric Furnace

Electric furnaces are a popular choice for many households, but like any appliance, they can run into problems from time to time. Keep reading for a short look at the five most common problems electric furnaces face and how to troubleshoot them before calling a repair service. By understanding these problems, you can potentially save time and money on unnecessary repairs.

Lack of Heat
If you turn on your furnace and it blows cold air, you should check the thermostat to ensure it is set to the correct temperature. Ensure the thermostat is correctly set before checking the air filter. A dirty filter can impede airflow, lowering your furnace's efficiency. If the filter is clean, the issue may lie with the heating element or blower motor.

Strange Noises
If you hear strange noises coming from your electric furnace, it could be a sign of a mechanical issue. Squealing, rattling, or banging noises could indicate a problem with the blower motor, fan belt, or bearings. It is important to address these noises as soon as possible to prevent further damage to your furnace.

Short Cycling
Short cycling occurs when your furnace repeatedly turns on and off without finishing a full heating cycle. This issue may stem from a clogged air filter, a faulty thermostat, or problems with the heat exchanger. Short cycling not only diminishes your furnace's efficiency but also accelerates wear and tear on its components.

Tripped Circuit Breaker
If your electric furnace suddenly stops working, it could be due to a tripped circuit breaker. Check your electrical panel to see if the furnace circuit breaker has tripped, and reset it if necessary. If the circuit breaker continues to trip, there could be a wiring issue or a problem with the furnace itself.

Ignition Problems
Electric furnaces rely on an ignition system to ignite the heating elements and produce heat. If your furnace isn't generating heat, it might be because of ignition issues. This could be caused by a faulty ignition system, a malfunctioning thermostat, or a problem with the heating elements. A repair service can troubleshoot the ignition system and make any necessary repairs to ensure your furnace is working correctly.

Electric furnaces can encounter a variety of problems that require repair services. By being aware of the common issues, such as lack of heat, strange noises, short cycling, tripped circuit breakers, and ignition problems, you can troubleshoot these problems before calling in a professional. However, if you are unsure of how to diagnose or fix these issues, it is always best to rely on a professional repair service to ensure your furnace is running efficiently and safely.
