Investigating Furnace Issues: Why Your Furnace Keeps Tripping Your Circuit Breaker

When your furnace keeps tripping the circuit breaker, it is vital to figure out the root of the problem immediately. Although resetting the breaker is an easy and convenient solution, it will not fix the underlying issue and will eventually cause the circuit breaker to trip again. Moreover, repeatedly resetting the breaker could damage your electrical equipment and cause a fire.

Instead of continuing to run your furnace, it’s best to disconnect the device from the outlet and contact a professional to have him or her inspect your heating system. Usually, a furnace would trip the breaker due to the following reasons:

Overloaded Furnace

An overloaded furnace draws electrical current beyond its capacity. When you have this kind of furnace, your machine will work only for a few seconds and then quickly trip the breaker. Several issues can lead to an overloaded furnace, including:

  • Malfunctioning Components – A defective part in your furnace is causing the heating system to draw more than the required electrical current.
  • Restricted Ductwork – Some ducts in your furnace may be responsible for restricting the airflow to and from your house.
  • Closed Air Vents – A closed air vent can make it difficult for your furnace to blow air into your home.
  • A Dirty Air Filter – A dirty filter clogs your furnace. It means that your machine has to work twice as hard to suck in air from your home.

A Shared, Overloaded Circuit

Another possibility you can look at is that your furnace may be sharing an electrical circuit with other outlets in your home. This shared circuit could pose a problem for you, as operating your furnace and a more massive electrical appliance (such as power tools) in the same circuit could lead to an electrical overload.

Ground Fault or Short Circuit in Your Furnace

When you observe that your furnace starts up but instantly trips the breaker, it could be due to a ground fault inside the furnace or an electrical short circuit. Ground faults occur when a grounded part in your furnace, such as a metal box, touches a ground wire. On the other hand, electrical short circuits happen when a neutral wire comes into contact with a bare hot wire.

The common issue between a short circuit and a ground fault is that they both significantly boost the amount of electrical current pulled by the furnace, which will eventually trip the breaker.
