4 Reasons Why Your Furnace is Tripping Your Circuit Breaker and How to Fix 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 average performance returns after you reset it, there is no immediate cause for concern. In this instance, an unforeseen power surge is typically the source.

However, you can’t avoid the situation if the breaker gets thrown over and over. This may happen with both electric and gas furnaces. After all, even gas-fired furnaces need electricity to operate the blower motor and other components. Before you arrange furnace repair, double check the most typical reasons your furnace would be throwing the circuit breaker and how you can stop it.

1. Overworked Furnace

Does your furnace work for a short time before flipping the breaker? This could imply limited airflow. A dirty filter or closed air vents require your furnace to work harder. The increased electrical draw may overload the system, strain the circuit andflip the breaker. Consider the following tips to restore unimpeded airflow and fix the issue:

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

2. Full Circuit

HVAC equipment should be on a dedicated 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 measure, you can unplug the secondary item or avoid using it while the furnace is in use. A smarter, more ongoing solution is to have an electrician put in 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 is frequently an electrical issue within the furnace. An exposed wire could be shorting out the circuit when it reaches a neutral wire or causes a ground fault if it comes into contact with a grounded wire or metal object. Either of these problems can affect the electrical draw enough to flip the circuit. You’ll need an HVAC specialist like Service Experts Heating & Air Conditioning to identify and fix the issue.

4. Electrical Panel Issue

If you rule out any problems with your furnace, the electrical panel could be the source. Shaky connections or malfunctioning breakers can lead to irregular performance. If you have an older house, you may need to have the panel replaced if it’s too old, damaged or incorrectly installed. In this case, you need assistance from an electrician.
