How to Fix / Troubleshooting
Safety first: Turn off power before inspecting moving parts. Do not insert hands or tools near a running fan.
- Inspect fan blade: Remove the top grille and check that the fan blade is tight on the motor shaft and not contacting the shroud.
- Remove debris: Clear any leaves, twigs, or foreign objects from the fan area.
- Check motor bearings: Spin the fan by hand with power off. Roughness or grinding indicates a failing motor that should be replaced.
- Compressor mounts: Inspect rubber mounting pads under the compressor. Replace if cracked or missing to reduce vibration noise.
