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

Tripped circuit breakers are frustrating and worrisome, namely if it seems like the furnace is the source. If your breaker shuts off once and average operation returns after you reset it, there is no immediate cause for distress. In this instance, an unrelated power surge is typically the source.

However, you can’t neglect the problem if the breaker flips repeatedly. This may happen with both electric and gas furnaces. After all, even gas-fired furnaces rely on electricity to run the blower motor and other parts. Before you arrange furnace repair, think about the most likely reasons your furnace could be tripping 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 be a result of restricted airflow. A dirty filter or closed air vents require your furnace to work harder. The higher electrical draw might overheat the system, strain the circuit andtrip the breaker. Try these tips to restore normal airflow and fix the issue:

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

2. Full Circuit

HVAC equipment is best used on a lone circuit, but this may not be the case in older houses. Review 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 using it while the furnace is in use. A better, more ongoing solution is to have an electrician install 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 issue within the furnace. An exposed wire may be shorting out the circuit when it brushes against a neutral wire or causes a ground fault if it meets a grounded wire or metal object. Either of these issues can affect the electrical draw enough to trip the circuit. You’ll want an HVAC Expert like R & M Climate Control Service Experts to diagnose and repair the problem.

4. Electrical Panel Problem

If you rule out any trouble with your furnace, the electrical panel might be the source. Poor connections or faulty breakers could 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 poorly installed. In this case, you need help from an electrician.
