Tripped circuit breakers are frustrating and stressful, namely if it seems like the furnace is the source. If your breaker shuts off once and usual function returns after you reset it, there is no immediate cause for unease. In this situation, a surprise power surge is probably the cause.
However, you can’t ignore the problem if the breaker flips again and again. This might happen with both electric and gas furnaces. After all, even gas-fired furnaces depend on electricity to operate the blower motor and other parts. Before you arrange furnace repair, double check the most typical reasons your furnace may be throwing the circuit breaker and how you can prevent it.
1. Overloaded Furnace
Does your furnace work for just a few minutes before throwing the breaker? This can imply restricted airflow. A dirty filter or closed air vents force your furnace to work harder. The increased electrical draw could overwork the system, strain the circuit andflip the breaker. Consider the following tips to restore consistent airflow and resolve the problem:
- Replace the air filter.
- Open all air registers and ensure none are blocked by furniture, curtains or rugs.
- Don’t leave anything against the furnace or otherwise block airflow into it.
2. Full Circuit
HVAC equipment is best used on its own circuit, but this may not be the case in older houses. Find the labels on your electrical panel to find out if another appliance shares a circuit with your furnace. As a brief precaution, you can unplug the secondary item or avoid using it while the furnace is running. A safer, more lasting solution is to have an electrician create a new 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 issue inside the furnace. An exposed wire could be shorting out the circuit when it touches a neutral wire or leads to a ground fault if it touches a grounded wire or metal object. Either of these problems can increase the electrical draw enough to trip the circuit. You’ll do best with an HVAC specialist like Norrell Service Experts to diagnose and repair the issue.
4. Electrical Panel Trouble
If you rule out any concerns with your furnace, the electrical panel might be the source. Poor connections or malfunctioning breakers might lead to inconsistent performance. If you own an older residence, you may need to have the panel replaced if it’s outdated, damaged or poorly installed. In this case, you need assistance from an electrician.
