Tripped circuit breakers are frustrating and stressful, particularly if it seems like the furnace is the source. If your breaker gets thrown once and usual operation returns after you reset it, there is no immediate cause for distress. In this situation, a surprise power surge is probably the cause.
However, you can’t neglect the situation if the breaker gets thrown over and over. This might 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 schedule furnace repair, review the most typical reasons your furnace might be throwing the circuit breaker and how you can stop it.
1. Overloaded Furnace
Does your furnace run for a brief time before tripping the breaker? This could stem from weak airflow. A dirty filter or closed air vents force your furnace to work harder. The larger electrical draw may overload the system, strain the circuit andflip the breaker. Here are some tips to restore proper airflow and fix the trouble:
- 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. Full Circuit
HVAC equipment should be on its own circuit, but this might not happen in older houses. Check the labels on your electrical panel to learn if another appliance shares a circuit with your furnace. As a temporary measure, you can unplug the secondary item or avoid operating it while the furnace is running. A better, more lasting solution is to have an electrician install a dedicated circuit for your HVAC system.
3. Short Circuit or Ground Fault
Does your furnace trip 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 surge the electrical draw enough to flip the circuit. You’ll do best with an HVAC Expert like Bob Brown Service Experts to find and repair the trouble.
4. Electrical Panel Problem
If you exclude any trouble with your furnace, the electrical panel might be the source. Poor connections or malfunctioning breakers may lead to inconsistent performance. If you have an older residence, you could need to have the panel replaced if it’s too old, damaged or incorrectly installed. In this case, you need help from an electrician.
