Tripped circuit breakers are irritating and stressful, especially if it seems like the furnace is the cause. If your breaker shuts off once and typical operation returns after you reset it, there is no immediate cause for alarm. In this instance, an unrelated power surge is probably the cause.
However, you can’t ignore 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 use electricity to power the blower motor and other components. Before you arrange furnace repair, review the most common reasons your furnace would be tripping the circuit breaker and how you can stop it.
Does your furnace start for just a few minutes before flipping the breaker? This can be a result of reduced airflow. A dirty filter or closed air vents compels your furnace to work harder. The increased electrical draw could overload the system, strain the circuit and trip the breaker. Here are some tips to restore consistent airflow and fix the problem:
HVAC equipment should be on its own circuit, but this might not occur in older homes. Inspect the labels on your electrical panel to learn if another appliance shares a circuit with your furnace. As an interim resolution, you can unplug the secondary item or avoid operating it while the furnace is working. A wiser, more ongoing solution is to have an electrician put in a dedicated circuit for your HVAC system.
Does your furnace trigger the circuit breaker as soon as it starts? This could be a result of an electrical problem within the furnace. An exposed wire might be shorting out the circuit when it reaches a neutral wire or creates a ground fault if it touches a grounded wire or metal object. Either of these problems can affect the electrical draw enough to trigger the circuit. You’ll do best with an HVAC pro like Service Experts Heating, Air Conditioning & Plumbing to find and repair the trouble.
If you exclude any trouble with your furnace, the electrical panel may be the source. Lax connections or malfunctioning breakers can lead to inconsistent performance. If you have an older home, you could need to have the panel replaced if it’s too old, damaged or incorrectly installed. In this case, you need assistance from an electrician.
