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

Tripped circuit breakers are annoying and worrisome, namely if it seems like the furnace is the culprit. If your breaker shuts off once and usual performance starts after you reset it, there is no immediate cause for unease. In this situation, an unrelated power surge is probably the cause.

However, you can’t neglect the situation if the breaker gets thrown repeatedly. This can 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 schedule furnace repair, review the most likely reasons your furnace might be blowing the circuit breaker and how you can handle it.

1. Overheated Furnace

Does your furnace start for a short time before flipping the breaker? This could be a result of weak airflow. A dirty filter or closed air vents compels your furnace to work harder. The resulting electrical draw could overwork the system, strain the circuit andtrip the breaker. Try these tips to restore unimpeded airflow and resolve the problem:

  • Change the air filter.
  • Open all air registers and ensure none are blocked by furniture, curtains or rugs.
  • Don’t place anything against the furnace or otherwise restrict airflow into it.

2. Overloaded Circuit

HVAC equipment is best used on its own circuit, but this might not occur in older houses. Find the labels on your electrical panel to find out if another appliance shares a circuit with your furnace. As an interim measure, you can unplug the secondary item or avoid operating it while the furnace is in use. A better, more ongoing solution is to have an electrician create a new circuit for your HVAC system.

3. Short Circuit or Ground Fault

Does your furnace trigger the circuit breaker immediately upon startup? This could be a result of an electrical malfunction inside the furnace. An exposed wire could be shorting out the circuit when it brushes against 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 increase the electrical draw enough to trigger the circuit. You’ll do best with an HVAC specialist like Service Experts Commercial HVAC to identify and resolve the trouble.

4. Electrical Panel Trouble

If you exclude any concerns with your furnace, the electrical panel might be the culprit. Loose connections or malfunctioning breakers will sometimes lead to inconsistent performance. If you own an older house, you might need to have the panel replaced if it’s too old, damaged or poorly installed. In this situation, you need the expertise of an electrician.
