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

Tripped circuit breakers are annoying and troublesome, namely if it seems like the furnace is the source. If your breaker trips once and average function starts after you reset it, there is no immediate cause for alarm. In this case, a surprise power surge is probably the cause.

However, you can’t avoid the issue if the breaker gets thrown multiple times. 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 request furnace repair, review the most common reasons your furnace could be tripping the circuit breaker and how you can stop it.

1. Overheated Furnace

Does your furnace work for a brief time before flipping the breaker? This might stem from restricted airflow. A dirty filter or closed air vents require your furnace to work harder. The larger electrical draw could overload the system, strain the circuit and trip the breaker. Try these tips to restore unimpeded airflow and fix the problem:

    • Swap out the air filter.
    • Open all air registers and make sure none are blocked by furniture, curtains or rugs.
    • Don’t place anything against the furnace or otherwise block airflow into it.

2. Overworked Circuit

HVAC equipment is best used on a lone circuit, but this might not occur in older residences. Inspect the labels on your electrical panel to learn if another appliance shares a circuit with your furnace. As a temporary resolution, you can unplug the secondary item or avoid running it while the furnace is working. A safer, more lasting solution is to have an electrician install an individual 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 issue in the furnace. An exposed wire might be shorting out the circuit when it brushes against a neutral wire or leads to a ground fault if it touches a grounded wire or metal object. Either of these problems can surge the electrical draw enough to flip the circuit. You’ll want an HVAC Expert like Winnipeg Supply Service Experts to uncover and resolve the problem.

4. Electrical Panel Trouble

If you rule out any malfunctions with your furnace, the electrical panel could be the culprit. Shaky connections or damaged breakers could lead to erratic performance. If you own an older residence, you might need to have the panel replaced if it’s obsolete, damaged or incorrectly installed. In this case, you need help from an electrician.
