4 Reasons Why Your Furnace is Throwing Your Circuit Breaker and How to Solve It
Tripped circuit breakers are annoying and stressful, particularly if it seems like the furnace is the source. If your breaker gets thrown once and average function starts after you reset it, there is no sudden cause for alarm. In this instance, a surprise power surge is probably the reason.
However, you can’t neglect the issue if the breaker gets thrown over and over. This may happen with both electric and gas furnaces. After all, even gas-fired furnaces use electricity to power the blower motor and other parts. Before you arrange furnace repair, review the most likely reasons your furnace may be throwing the circuit breaker and how you can avoid it.
1. Overworked Furnace
Does your furnace work for just a few minutes before throwing the breaker? This can stem from poor airflow. A dirty filter or closed air vents require your furnace to work harder. The higher electrical draw can overwork the system, strain the circuit and throw the breaker. Here are some tips to restore normal airflow and resolve the issue:
- Replace the air filter.
- Open all air registers and make certain none are obstructed by furniture, curtains or rugs.
- Don’t place anything against the furnace or otherwise impede airflow into it.
2. Overworked Circuit
HVAC equipment does best on its own circuit, but this might not happen in older houses. Review the labels on your electrical panel to learn if another appliance shares a circuit with your furnace. As a brief precaution, you can unplug the secondary item or avoid running it while the furnace is on. A better, more lasting solution is to have an electrician put in a new circuit for your HVAC system.
3. Short Circuit or Ground Fault
Does your furnace flip the circuit breaker as soon as it starts? This is frequently an electrical issue within the furnace. An exposed wire might be shorting out the circuit when it brushes against a neutral wire or creates a ground fault if it touches a grounded wire or metal object. Either of these things can affect the electrical draw enough to trigger the circuit. You’ll want an HVAC pro like Service Experts Heating, Air Conditioning & Plumbing to identify and fix the issue.
4. Electrical Panel Problem
If you eliminate any issues with your furnace, the electrical panel could be the culprit. Shaky connections or damaged breakers can lead to inconsistent performance. If you have an older house, you may need to have the panel replaced if it’s too old, damaged or poorly installed. In this instance, you need assistance from an electrician.
