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.
