How to Fix / Troubleshooting
Safety: Isolate power before inspecting the outdoor unit. Moving parts and high voltage are present.
- Inspect fan: Check for sticks, leaves, or plastic caught in the fan. Remove obstructions.
- Check fan blade: Ensure the blade is tight on the motor shaft and not cracked. Tighten the hub screw if loose.
- Spin test: With power off, spin the fan by hand. Roughness or noise indicates bearing wear; replace the AEG outdoor fan motor.
- Compressor noise: If noise clearly comes from the compressor shell, especially at startup, internal wear may be present. This requires professional evaluation.
