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

Tripped circuit breakers are aggravating and troublesome, particularly if it seems like the furnace is the cause. If your breaker gets thrown once and typical performance returns after you reset it, there is no immediate cause for unease. In this case, a surprise power surge is typically the reason.

However, you can’t neglect the issue if the breaker gets thrown again and again. This might happen with both electric and gas furnaces. After all, even gas-fired furnaces utilize electricity to run the blower motor and other pieces. Before you schedule furnace repair, review the most common reasons your furnace would be throwing the circuit breaker and how you can stop it.

1. Overworked Furnace

Does your furnace work for a brief time before flipping the breaker? This could point to weak airflow. A dirty filter or closed air vents compels your furnace to work harder. The higher electrical draw might overload the system, strain the circuit andflip the breaker. Here are some tips to restore proper airflow and resolve the trouble:

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

2. Overloaded Circuit

HVAC equipment does best on a lone circuit, but this might not happen in older homes. Check the labels on your electrical panel to find out 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 in use. A wiser, more lasting solution is to have an electrician put in an individual circuit for your HVAC system.

3. Short Circuit or Ground Fault

Does your furnace trip the circuit breaker immediately upon startup? This points to an electrical problem in the furnace. An exposed wire may be shorting out the circuit when it reaches a neutral wire or creates 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 be better off with an HVAC Expert like All American Air Service Experts to find and resolve the problem.

4. Electrical Panel Issue

If you eliminate any concerns with your furnace, the electrical panel could be the culprit. Shaky connections or faulty breakers may lead to erratic performance. If you live in an older residence, you might need to have the panel replaced if it’s outdated, damaged or poorly installed. In this instance, you need the expertise of an electrician.
