Possible Causes
Loose fan blade or blower wheel, foreign object in blower, loose mounting screws, failing fan motor bearings, compressor mounting issues
How to Fix / Troubleshooting
Safety: Unplug the unit before inspecting moving parts. Keep fingers and tools away from fan blades.
Steps:
- Check for loose panels: Tighten all exterior screws and mounting brackets. Loose sheet metal often causes rattles.
- Inspect blower and fan: Remove the front cover and look for debris in the blower wheel. Ensure the wheel and outdoor fan blade are tight on their shafts.
- Fan motor bearings: Spin the blower and fan by hand. Roughness or play indicates worn bearings; replace the motor assembly.
- Compressor noise: A loud knocking or metallic noise from the compressor often indicates internal damage and usually requires replacement of the sealed system by a professional.
