How to Fix / Troubleshooting
Safety: Turn off power at the breaker before working on the outdoor unit.
Steps:
- Inspect fan area: Remove the top grille if necessary and check for leaves, plastic, or other debris contacting the fan blade.
- Check blade clearance: Ensure the fan blade is not rubbing against the shroud. Gently bend the shroud or reposition the blade if misaligned.
- Tighten hub: Verify the fan blade is firmly secured to the motor shaft; tighten the set screw or nut if loose.
- Replace motor: If noise persists and the motor feels rough when turned by hand, replace the outdoor fan motor with a Kelvinator-compatible unit.
