How to Fix / Troubleshooting
Safety: Repeated breaker tripping is a fire hazard. Do not replace a breaker with a larger size.
Steps:
- Isolate circuit: Ensure the furnace is on a dedicated circuit with no other large loads.
- Inspect wiring: With power off, check for rubbed or pinched wires in the blower and inducer compartments.
- Motor tests (advanced): A technician can measure motor amp draw and insulation resistance to identify a failing motor.
If the breaker continues to trip, contact a professional immediately to locate and repair the fault.
