Tripped circuit breakers are annoying and stressful, namely if it seems like the furnace is the cause. If your breaker shuts off once and regular operation starts after you reset it, there is no abrupt cause for concern. In this situation, a surprise power surge is probably the reason.
However, you can’t ignore the situation if the breaker trips repeatedly. This may happen with both electric and gas furnaces. After all, even gas-fired furnaces require electricity to run the blower motor and other components. Before you request furnace repair, think about the most likely reasons your furnace might be throwing the circuit breaker and how you can prevent it.
1. Overworked Furnace
Does your furnace start for just a few minutes before flipping the breaker? This can be a result of reduced airflow. A dirty filter or closed air vents compels your furnace to work harder. The increased electrical draw can overload the system, strain the circuit andtrip the breaker. Consider the following tips to restore normal airflow and take care of the issue:
- Change the air filter.
- Open all air registers and make sure none are restricted by furniture, curtains or rugs.
- Don’t place anything against the furnace or otherwise impede airflow into it.
2. Overloaded Circuit
HVAC equipment should be on a lone circuit, but this might not occur in older residences. Review the labels on your electrical panel to find out if another appliance shares a circuit with your furnace. As an interim precaution, you can unplug the secondary item or avoid operating it while the furnace is running. A better, more lasting solution is to have an electrician install an individual circuit for your HVAC system.
3. Short Circuit or Ground Fault
Does your furnace flip the circuit breaker immediately upon startup? This may be evidence of an electrical issue inside the furnace. An exposed wire could be shorting out the circuit when it reaches a neutral wire or leads to a ground fault if it comes into contact with a grounded wire or metal object. Either of these issues can increase the electrical draw enough to trigger the circuit. You’ll do best with an HVAC specialist like Strand Brothers Service Experts to identify and repair the problem.
4. Electrical Panel Issue
If you eliminate any problems with your furnace, the electrical panel may be the source. Lax connections or damaged breakers will sometimes lead to finicky performance. If you have an older home, you may need to have the panel replaced if it’s outdated, damaged or poorly installed. In this case, you need assistance from an electrician.
