4 Reasons Why Your Furnace is Tripping Your Circuit Breaker and How to Fix It
Tripped circuit breakers are irritating and troublesome, namely if it seems like the furnace is the source. If your breaker shuts off once and usual performance starts after you reset it, there is no immediate cause for distress. In this situation, an unrelated power surge is probably the cause.
However, you can’t neglect the problem if the breaker flips multiple times. This can happen with both electric and gas furnaces. After all, even gas-fired furnaces utilize electricity to power the blower motor and other pieces. Before you arrange furnace repair, double check the most typical reasons your furnace might be throwing the circuit breaker and how you can prevent it.
1. Overheated Furnace
Does your furnace work for a short time before tripping the breaker? This can stem from limited airflow. A dirty filter or closed air vents compels your furnace to work harder. The larger electrical draw might overheat the system, strain the circuit and flip the breaker. Here are some tips to restore proper airflow and resolve the issue:
- Change the air filter.
- Open all air registers and make sure none are blocked by furniture, curtains or rugs.
- Don’t put anything against the furnace or otherwise reduce airflow into it.
2. Overworked Circuit
HVAC equipment does best on a lone circuit, but this might not happen in older residences. Examine 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 running it while the furnace is on. A wiser, more permanent solution is to have an electrician put in a dedicated circuit for your HVAC system.
3. Short Circuit or Ground Fault
Does your furnace flip the circuit breaker right as it begins running? This could be a result of an electrical problem in the furnace. An exposed wire could be shorting out the circuit when it touches a neutral wire or creates a ground fault if it touches a grounded wire or metal object. Either of these problems can surge the electrical draw enough to flip the circuit. You’ll be better off with an HVAC professional like Service Experts Heating, Air Conditioning & Plumbing to find and fix the problem.
4. Electrical Panel Trouble
If you eliminate any trouble with your furnace, the electrical panel may be to blame. Poor connections or faulty breakers might lead to irregular performance. If you live in an older residence, you could need to have the panel replaced if it’s outdated, damaged or incorrectly installed. In this instance, you need the expertise of an electrician.
