Tripped circuit breakers are frustrating and troublesome, especially if it seems like the furnace is the culprit. If your breaker gets thrown once and regular performance returns after you reset it, there is no immediate cause for concern. In this case, an unrelated power surge is typically the reason.
However, you can’t avoid the issue if the breaker flips over and over. This can happen with both electric and gas furnaces. After all, even gas-fired furnaces depend on electricity to power the blower motor and other components. Before you schedule furnace repair, review the most likely reasons your furnace might be throwing the circuit breaker and how you can prevent it.
Does your furnace run for just a few minutes before throwing the breaker? This might be a result of restricted airflow. A dirty filter or closed air vents require your furnace to work harder. The higher electrical draw can overload the system, strain the circuit and flip the breaker. Consider the following tips to restore proper airflow and fix the trouble:
HVAC equipment does best on a lone circuit, but this might not happen in older houses. Check 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 working. A wiser, more ongoing solution is to have an electrician put in a dedicated circuit for your HVAC system.
Does your furnace trigger the circuit breaker immediately upon startup? This could be a result of an electrical issue inside the furnace. An exposed wire may be shorting out the circuit when it reaches a neutral wire or leads to a ground fault if it comes into contact with 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 professional like Service Experts Heating, Air Conditioning & Plumbing to diagnose and repair the problem.
If you eliminate any malfunctions with your furnace, the electrical panel may be to blame. Lax connections or faulty breakers could lead to erratic performance. If you live in an older residence, you might need to have the panel replaced if it’s obsolete, damaged or incorrectly installed. In this situation, you need help from an electrician.
