4 Reasons Why Your Furnace is Tripping Your Circuit Breaker and How to Solve It
Tripped circuit breakers are annoying and stressful, namely if it seems like the furnace is the culprit. If your breaker shuts off once and average performance returns after you reset it, there is no sudden cause for concern. In this case, an unforeseen power surge is typically the cause.
However, you can’t ignore the issue if the breaker flips repeatedly. This can happen with both electric and gas furnaces. After all, even gas-fired furnaces need electricity to operate the blower motor and other pieces. Before you arrange furnace repair, think about the most likely reasons your furnace may 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 might stem from reduced airflow. A dirty filter or closed air vents require your furnace to work harder. The higher electrical draw may overload the system, strain the circuit and trip the breaker. Try these tips to restore normal airflow and fix the trouble:
- Change the air filter.
- Open all air registers and make certain none are restricted by furniture, curtains or rugs.
- Don’t place anything against the furnace or otherwise block airflow into it.
2. Full Circuit
HVAC equipment should be on a dedicated circuit, but this might not occur in older houses. Inspect the labels on your electrical panel to find out if another appliance shares a circuit with your furnace. As a brief resolution, you can unplug the secondary item or avoid operating it while the furnace is working. A better, 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 trip the circuit breaker right as it begins running? This is frequently an electrical malfunction inside the furnace. An exposed wire could be shorting out the circuit when it reaches a neutral wire or causes a ground fault if it meets a grounded wire or metal object. Either of these issues can surge the electrical draw enough to trip the circuit. You’ll be better off with an HVAC professional like Service Experts Heating, Air Conditioning & Plumbing to identify and fix the trouble.
4. Electrical Panel Trouble
If you rule out any trouble with your furnace, the electrical panel might be the source. Poor connections or malfunctioning breakers can lead to finicky performance. If you live in an older house, you could need to have the panel replaced if it’s obsolete, damaged or inadequately installed. In this case, you need the expertise of an electrician.
