The Top Reasons Why Your Furnace Could Trip Your Circuit Breaker, and What To Do Next

ICSNY • Jan 13, 2023

When you think about items that can trip your circuit breaker, there are a few examples that come to mind. Maybe the occasional power strip, hair dryer, or big screen TV could overload your circuit breaker, causing it to trip. You probably do not expect your furnace to trip your circuit breaker, but it can happen from time to time.


What are a few of the top reasons why your furnace could cause your circuit breaker to trip, and what should you do about it?

1. Your Furnace Is Working Too Hard

Your furnace will cause your circuit breaker to trip if it is drawing too much electricity for your home’s electrical system to handle. So, what are some of the most common reasons why your furnace might be drawing too much electricity?


A few of the most common reasons include:


  • There might be a problem with your ductwork, restricting the airflow throughout your home.
  • There might be a component that is not working properly in the furnace itself.
  • Your air filter might be clogged, forcing your furnace to work too hard.
  • There could be a blocked air vent that places a tremendous amount of stress on your furnace.
  • If you need help cleaning your furnace to address these issues, count on our team to assist you.

2. There Is a Ground Fault or Short Circuit in the Furnace

It is also possible that there could be an issue with the intrinsic wiring of your furnace. For example, there might be a problem with your ground fault, or there might be a short circuit in the furnace itself. Electrical wiring has come a long way during the past few years, and there is a chance that your old furnace might not be compatible with the new electrical system in your home. Or, the reverse could be true.


It is important to reach out to an expert if you need someone who can take a look at your furnace's electrical system and identify the problem. It would be our pleasure to assist you, so do not hesitate to reach out to us when you need someone to help you with the electricity of your furnace.

3. Your Furnace Is Sharing a Circuit

If you want your furnace to work appropriately, it is best to put it on its own circuit. On the other hand, if you have an older home, there is a chance that your furnace could be sharing an electrical circuit with other devices in your home.


If you recently connected some large appliances to the same circuit as your furnace, your circuit could trip. It would be our pleasure to take a look at how your circuit is set up, compare it to your furnace, and make sure everything is working as it should.

4. The Issue Is With Your Circuit Breaker

Finally, there is a chance that your furnace might be working appropriately, but there could be an issue with your circuit breaker. If you believe something is wrong with your circuit breaker, you need to reach out to a professional electrician who can address it for you.
