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

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

However, you can’t avoid the situation if the breaker trips repeatedly. This may happen with both electric and gas furnaces. After all, even gas-fired furnaces count on electricity to run the blower motor and other pieces. Before you request furnace repair, think about the most common reasons your furnace may be tripping the circuit breaker and how you can prevent it.

1. Overloaded Furnace

Does your furnace work for a brief time before flipping the breaker? This might indicate reduced airflow. A dirty filter or closed air vents compels your furnace to work harder. The larger electrical draw may overwork the system, strain the circuit andflip the breaker. Here are some tips to restore consistent airflow and resolve the issue:

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

2. Overworked Circuit

HVAC equipment should be on a dedicated circuit, but this might not occur in older houses. Check the labels on your electrical panel to find out if another appliance shares a circuit with your furnace. As an interim precaution, you can unplug the secondary item or avoid operating it while the furnace is in use. A smarter, more permanent solution is to have an electrician create an individual circuit for your HVAC system.

3. Short Circuit or Ground Fault

Does your furnace flip the circuit breaker as soon as it starts? This may be evidence of an electrical malfunction in the furnace. An exposed wire may be shorting out the circuit when it touches a neutral wire or creates a ground fault if it touches a grounded wire or metal object. Either of these issues can increase the electrical draw enough to trip the circuit. You’ll want an HVAC professional like Service Experts Heating & Air Conditioning to diagnose and resolve the issue.

4. Electrical Panel Trouble

If you eliminate any malfunctions with your furnace, the electrical panel might be to blame. Loose connections or damaged breakers may lead to inconsistent performance. If you live in an older house, you might need to have the panel replaced if it’s outdated, damaged or incorrectly installed. In this instance, you need assistance from an electrician.
