4 Reasons Why Your Furnace is Shutting Off Your Circuit Breaker and How to Solve It

Tripped circuit breakers are aggravating and troublesome, especially if it seems like the furnace is the cause. If your breaker shuts off once and regular performance resumes after you reset it, there is no immediate cause for unease. In this case, an unforeseen power surge is the most likely reason.

However, you can’t ignore the problem if the breaker gets thrown over and over. This might happen with both electric and gas furnaces. After all, even gas-fired furnaces require electricity to run the blower motor and other pieces. Before you arrange furnace repair, double check the most typical reasons your furnace would be blowing the circuit breaker and how you can prevent it.

1. Overloaded Furnace

Does your furnace start for a short time before tripping the breaker? This may imply restricted airflow. A dirty filter or closed air vents force your furnace to work harder. The larger electrical draw may overwork the system, strain the circuit andthrow the breaker. Try these tips to restore unimpeded airflow and resolve the problem:

  • Replace the air filter.
  • Open all air registers and ensure none are obstructed by furniture, curtains or rugs.
  • Don’t put anything against the furnace or otherwise reduce airflow into it.

2. Overworked Circuit

HVAC equipment should be on a dedicated circuit, but this may not be the case in older homes. Check the labels on your electrical panel to determine if another appliance shares a circuit with your furnace. As a temporary resolution, you can unplug the secondary item or avoid operating it while the furnace is working. A better, more permanent solution is to have an electrician create a dedicated circuit for your HVAC system.

3. Short Circuit or Ground Fault

Does your furnace flip the circuit breaker as soon as it starts? This could be a result of an electrical malfunction in the furnace. An exposed wire might be shorting out the circuit when it brushes against a neutral wire or causes a ground fault if it comes into contact with a grounded wire or metal object. Either of these issues can surge the electrical draw enough to flip the circuit. You’ll do best with an HVAC specialist like D.A. Bennett Service Experts to diagnose and repair the trouble.

4. Electrical Panel Issue

If you rule out any malfunctions with your furnace, the electrical panel could be the source. Lax connections or faulty breakers might lead to inconsistent performance. If you own an older home, you may need to have the panel replaced if it’s obsolete, damaged or incorrectly installed. In this situation, you need assistance from an electrician.
