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

Tripped circuit breakers are aggravating and worrisome, namely if it seems like the furnace is the source. If your breaker shuts off once and average function returns after you reset it, there is no immediate cause for concern. In this case, a surprise power surge is the most likely source.

However, you can’t neglect the problem if the breaker flips multiple times. This might 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 request furnace repair, consider the most common reasons your furnace would be throwing the circuit breaker and how you can stop it.

1. Overloaded Furnace

Does your furnace start for a short time before flipping the breaker? This might stem from restricted airflow. A dirty filter or closed air vents force your furnace to work harder. The resulting electrical draw might overheat the system, strain the circuit andflip the breaker. Here are some tips to restore consistent airflow and take care of the issue:

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

2. Overworked Circuit

HVAC equipment is best used on a dedicated circuit, but this may not be the case in older houses. Examine the labels on your electrical panel to find out if another appliance shares a circuit with your furnace. As a temporary measure, you can unplug the secondary item or avoid running it while the furnace is working. A wiser, more lasting solution is to have an electrician create a dedicated circuit for your HVAC system.

3. Short Circuit or Ground Fault

Does your furnace trip the circuit breaker as soon as it starts? This may be evidence of an electrical problem within the furnace. An exposed wire might be shorting out the circuit when it reaches a neutral wire or creates a ground fault if it touches a grounded wire or metal object. Either of these issues can surge the electrical draw enough to trigger the circuit. You’ll do best with an HVAC Expert like Golden Seal Service Experts to diagnose and fix the problem.

4. Electrical Panel Trouble

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