Tripped circuit breakers are irritating and worrisome, especially if it seems like the furnace is the source. If your breaker gets thrown once and normal function returns after you reset it, there is no immediate cause for concern. In this case, an unrelated power surge is probably the cause.
However, you can’t neglect the situation if the breaker flips repeatedly. This may happen with both electric and gas furnaces. After all, even gas-fired furnaces count on electricity to power the blower motor and other parts. Before you request furnace repair, consider the most common reasons your furnace could be throwing the circuit breaker and how you can stop it.
1. Overloaded Furnace
Does your furnace work for just a few minutes before throwing the breaker? This can be a result of restricted airflow. A dirty filter or closed air vents compels your furnace to work harder. The increased electrical draw could overheat the system, strain the circuit andflip the breaker. Consider the following tips to restore steady airflow and take care of the issue:
- Change the air filter.
- Open all air registers and ensure none are blocked by furniture, curtains or rugs.
- Don’t leave anything against the furnace or otherwise block airflow into it.
2. Overloaded Circuit
HVAC equipment should be on a dedicated circuit, but this might not occur in older homes. Check the labels on your electrical panel to determine if another appliance shares a circuit with your furnace. As a temporary measure, you can unplug the secondary item or avoid operating it while the furnace is in use. 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 trip the circuit breaker right as it begins running? This is frequently an electrical problem in the furnace. An exposed wire may be shorting out the circuit when it brushes against a neutral wire or creates a ground fault if it comes into contact with a grounded wire or metal object. Either of these issues can affect the electrical draw enough to flip the circuit. You’ll be better off with an HVAC specialist like Service Experts Home Services by Enercare to diagnose and resolve the trouble.
4. Electrical Panel Trouble
If you exclude any trouble with your furnace, the electrical panel might be the source. Poor connections or damaged breakers could lead to finicky performance. If you live in an older house, you may need to have the panel replaced if it’s outdated, damaged or poorly installed. In this instance, you need the expertise of an electrician.
