Tripped circuit breakers are frustrating and worrisome, particularly if it seems like the furnace is the source. If your breaker shuts off once and normal operation resumes after you reset it, there is no abrupt cause for concern. In this situation, an unforeseen power surge is the most likely reason.
However, you can’t avoid the problem if the breaker flips multiple times. This can happen with both electric and gas furnaces. After all, even gas-fired furnaces use electricity to run the blower motor and other pieces. Before you schedule furnace repair, think about the most likely reasons your furnace would be blowing the circuit breaker and how you can handle it.
1. Overheated Furnace
Does your furnace work for a brief time before flipping the breaker? This might indicate reduced 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 andthrow the breaker. Here are some tips to restore proper airflow and fix the problem:
- Change the air filter.
- Open all air registers and make certain none are restricted by furniture, curtains or rugs.
- Don’t put anything against the furnace or otherwise block airflow into it.
2. Overworked Circuit
HVAC equipment is best used on a lone circuit, but this might not happen in older houses. Inspect the labels on your electrical panel to find out if another appliance shares a circuit with your furnace. As an interim measure, you can unplug the secondary item or avoid running it while the furnace is on. A smarter, more lasting solution is to have an electrician put in an individual circuit for your HVAC system.
3. Short Circuit or Ground Fault
Does your furnace flip the circuit breaker right as it begins running? This is frequently an electrical issue within 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 affect the electrical draw enough to trigger the circuit. You’ll need an HVAC specialist like Abbey Air Home Services by Enercare to diagnose and fix the problem.
4. Electrical Panel Problem
If you rule out any malfunctions with your furnace, the electrical panel might be the culprit. Loose connections or damaged breakers could lead to finicky performance. If you live in an older home, you could need to have the panel replaced if it’s obsolete, damaged or incorrectly installed. In this case, you need assistance from an electrician.
