Possible Causes
Shorted blower motor windings, Shorted inducer motor on Wolf furnace, Pinched line-voltage wiring, Faulty 24V transformer drawing excessive current
How to Fix / Troubleshooting
Safety: Do not repeatedly reset a breaker that trips immediately. Turn off the breaker and investigate.
- Visual inspection: With power off, inspect all visible wiring for burns, melted insulation, or pinched cables.
- Motor isolation: Disconnect the blower motor and inducer motor one at a time (with power off), then restore power to see if the breaker still trips. This helps identify a shorted motor.
- Component replacement: Replace any Wolf motor or transformer that shows signs of shorting or overheating.
- Professional service: If the cause is not obvious, have a qualified electrician or HVAC technician trace the circuit.
