4 Reasons Why Your Furnace is Throwing Your Circuit Breaker and How to Fix It

Tripped circuit breakers are annoying and troublesome, particularly if it seems like the furnace is the source. If your breaker gets thrown once and normal performance starts after you reset it, there is no sudden cause for unease. In this instance, a surprise power surge is probably the cause.

However, you can’t ignore the situation if the breaker gets thrown again and again. This can happen with both electric and gas furnaces. After all, even gas-fired furnaces require electricity to power the blower motor and other pieces. Before you arrange furnace repair, consider the most typical reasons your furnace would be blowing the circuit breaker and how you can avoid it.

1. Overworked Furnace

Does your furnace start for just a few minutes before throwing the breaker? This may indicate poor airflow. A dirty filter or closed air vents compels your furnace to work harder. The larger electrical draw might overload the system, strain the circuit andflip the breaker. Try these tips to restore unimpeded airflow and take care of the issue:

  • Change the air filter.
  • Open all air registers and make certain none are blocked by furniture, curtains or rugs.
  • Don’t leave anything against the furnace or otherwise restrict airflow into it.

2. Overworked Circuit

HVAC equipment is best used on a lone circuit, but this might not happen in older homes. Check the labels on your electrical panel to determine if another appliance shares a circuit with your furnace. As a brief precaution, you can unplug the secondary item or avoid using it while the furnace is running. A smarter, more ongoing solution is to have an electrician create a new circuit for your HVAC system.

3. Short Circuit or Ground Fault

Does your furnace trip the circuit breaker as soon as it starts? This could be a result of an electrical problem in the furnace. An exposed wire might be shorting out the circuit when it touches a neutral wire or leads to a ground fault if it meets a grounded wire or metal object. Either of these issues can affect the electrical draw enough to trigger the circuit. You’ll do best with an HVAC Expert like Service Experts Heating & Air Conditioning to identify and resolve the problem.

4. Electrical Panel Trouble

If you rule out any issues with your furnace, the electrical panel might be the culprit. Loose connections or damaged breakers could lead to erratic performance. If you own an older residence, you could need to have the panel replaced if it’s too old, damaged or poorly installed. In this case, you need the expertise of an electrician.
