4 Reasons Why Your Furnace is Shutting Off Your Circuit Breaker and How to Fix It
Tripped circuit breakers are annoying and worrisome, particularly if it seems like the furnace is the source. If your breaker shuts off once and average performance returns after you reset it, there is no abrupt cause for distress. In this situation, an unforeseen power surge is typically the source.
However, you can’t ignore the problem if the breaker trips repeatedly. This can happen with both electric and gas furnaces. After all, even gas-fired furnaces need electricity to run the blower motor and other pieces. Before you arrange furnace repair, review the most typical reasons your furnace may be tripping 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 imply weak airflow. A dirty filter or closed air vents require your furnace to work harder. The resulting electrical draw might overload the system, strain the circuit andthrow the breaker. Consider the following tips to restore steady airflow and fix the problem:
- Replace the air filter.
- Open all air registers and ensure none are blocked by furniture, curtains or rugs.
- Don’t lean anything against the furnace or otherwise impede airflow into it.
2. Overloaded Circuit
HVAC equipment should be on a dedicated circuit, but this might not happen in older houses. Review the labels on your electrical panel to determine if another appliance shares a circuit with your furnace. As an interim resolution, you can unplug the secondary item or avoid running it while the furnace is running. A wiser, more ongoing 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 could be a result of an electrical problem within 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 touches a grounded wire or metal object. Either of these problems can surge the electrical draw enough to trigger the circuit. You’ll be better off with an HVAC pro like Chief/Bauer Service Experts to find and repair the trouble.
4. Electrical Panel Issue
If you rule out any concerns with your furnace, the electrical panel may be the source. Shaky connections or malfunctioning breakers will sometimes lead to erratic performance. If you live in an older residence, you might need to have the panel replaced if it’s too old, damaged or inadequately installed. In this instance, you need the expertise of an electrician.
