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

Tripped circuit breakers are aggravating and stressful, particularly if it seems like the furnace is the source. If your breaker shuts off once and regular operation resumes after you reset it, there is no sudden cause for unease. In this case, an unrelated power surge is the most likely source.

However, you can’t neglect the situation if the breaker flips repeatedly. This may happen with both electric and gas furnaces. After all, even gas-fired furnaces count on electricity to run the blower motor and other pieces. Before you schedule furnace repair, double check the most common reasons your furnace might be throwing the circuit breaker and how you can prevent it.

1. Overheated Furnace

Does your furnace run for a short time before tripping the breaker? This might be a result of poor airflow. A dirty filter or closed air vents force your furnace to work harder. The higher electrical draw may overwork the system, strain the circuit andtrip the breaker. Here are some tips to restore unimpeded airflow and take care of the problem:

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

2. Overworked Circuit

HVAC equipment is best used on its own circuit, but this may not be the case in older residences. Examine the labels on your electrical panel to find out if another appliance shares a circuit with your furnace. As a brief measure, you can unplug the secondary item or avoid operating it while the furnace is running. A wiser, more permanent solution is to have an electrician install a new circuit for your HVAC system.

3. Short Circuit or Ground Fault

Does your furnace flip the circuit breaker immediately upon startup? This points to an electrical malfunction in the furnace. An exposed wire could be shorting out the circuit when it reaches 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 flip the circuit. You’ll need an HVAC specialist like Broad Ripple Service Experts to identify and resolve the problem.

4. Electrical Panel Problem

If you exclude any problems with your furnace, the electrical panel might be the culprit. Poor connections or damaged breakers will sometimes lead to irregular performance. If you own an older residence, you might need to have the panel replaced if it’s outdated, damaged or inadequately installed. In this case, you need help from an electrician.
