Symptom
High-pitched squealing or whirring noise while running.
Fan or Pump Bearing Wear
Symptom
Ice cubes are too large and may jam the mechanism.
Excessive Ice Thickness
Symptom
Ice cubes are too small or hollow.

Reduced Cooling Capacity / Inefficient Operation
Symptom
Ice maker powers on but will not start the ice-making cycle (no water fill, no compressor).
Control Logic / Start-Up Failure
Symptom
Ice maker runs but makes no ice at all (compressor may or may not run).
No Ice Production
Symptom
Ice maker vibrates excessively or rattles against surfaces.
Excessive Vibration / Poor Leveling
Symptom
Ice melts quickly in the bin, or the bin is warm.
