6 Reasons Your Furnace Keeps Tripping Your Circuit Breaker

Furnaces partly rely on electricity to operate. Therefore, its functionality can halt if the circuit breaker trips, leaving your home helpless against the cold. A simple furnace reset should get it back to normal if the reason is a rare power surge. However, resets aren’t enough if the furnace trips circuit breaker repeatedly. This is a possibly dangerous situation that should be thoroughly investigated. The reason for the issue should be determined so a permanent solution can be implemented. A professional can help you with this task. Keep reading to learn all you need to know about this issue.

Why Does My Furnace Need Electricity In The First Place?

Furnaces mainly consume fuel for home heating, but some parts need electricity. Cutting off the power supply means the system cannot work correctly. It requires uninterrupted electrical power for optimal results.

  • Blower Motor: All furnaces have a blower motor that runs on electricity. This component sends warm air throughout your home. Without power, the motor will stop, and the heated air will stay near the furnace instead of getting distributed across the building.
  • Electronic Ignition: Older furnaces have pilot lights for ignition. On the other hand, electronic ignition has largely replaced this in modern heating systems. Electronic ignitions are more dependable but rely on electricity from the grid. This means you cannot turn on your furnace without power.

1. Clogged Furnace Filter

A clogged filter may be pushing the furnace to work too hard. Dirt buildup on the filter surface can prevent unrestricted airflow, making the system use more power to compensate and increase its heating performance. This can cause circuit overload, which can trip the breaker. Check the HVAC filters once a month and replace them as needed.

2. Blocked HVAC Air Vents Or Registers

Blocked air vents or vents at different points across the system can cause the same issue. The furnace is forced to work harder to heat your home and use more power. Check if furniture, closed curtains, or other things are blocking the vents. Remove them so normal airflow can resume.

3. Issues With Your Furnace Motor

You may have a faulty furnace motor. There may be worn wiring after years of service. This can cause shorts and other problems that may trip the circuit breaker.

4. HVAC Ductwork Is Leaking

Air leaks cause furnace inefficiency. The furnace will work harder to replace the heated air that gets lost continuously. This extra workload can force the circuit breaker to trip.

5. Electric Panel Needs A Repair

There may be cases when the furnace isn’t the reason, so you have to look elsewhere. The electrical panel may be the cause of the problem. A malfunctioning panel needs to be repaired by a professional right away.

6. Overloaded, Shared Circuit

A furnace consumes a lot of power. Therefore, furnaces should have their own circuit because sharing it with other appliances can overload the circuit. Ensure that appliances like power tools and lights do not share the furnace’s circuit.

What You Should Do If Your Furnace Trips The Circuit Breaker

Here are the steps to take if your furnace trips your breaker: 

  • Check The Furnace Air Filter: Habitually conduct regular air filter checks. Dirt accumulates on the filter’s surface. The airflow will suffer when the buildup gets bad.
  • Ensure HVAC Air Vents Have Proper Airflow And Aren’t Obstructed: Remove curtains, plants, furniture, or other obstructions blocking the vents. Ensure that the vents are open in all rooms, even those in unoccupied areas.
  • Contact An HVAC Contractor For A Professional Ductwork Inspection: Ducts can be challenging to care for. Call an HVAC professional to do an inspection and cleaning when needed. They can finish the task swiftly and efficiently.
  • Call An HVAC Professional For Furnace Repair: Novices can make things worse instead of better. You may think that doing DIY repairs saves you money, but you may have to spend more in the long run. Leave furnace electrical issues to the capable hands of a professional. They can provide fast and reliable solutions.
