How to Fix / Troubleshooting
Safety: A tripping breaker indicates a potential electrical fault. Do not repeatedly reset the breaker.
Steps:
- Observe pattern: Note whether the breaker trips exactly when the blower starts.
- Inspect blower: With power off, try to spin the blower wheel by hand. It should rotate freely. Stiff or seized movement indicates motor or bearing failure.
- Do not upsize breaker: Never install a larger breaker to stop nuisance trips.
- Professional repair: A technician should test motor current draw and replace the blower motor or capacitor as needed.
