Important Tips for Lg Models

  • LG official documentation describes certain ice dropping and normal operational sounds that may appear loud but are expected during harvest cycles.

Possible Causes

Ice cubes falling into bin (normal operational noise)

How to Identify: Noise occurs only when ice drops into the storage bin, periodic clicking or light thud.

Part: Ice maker assembly / ice bin

Improper leveling or vibration of refrigerator

How to Identify: Vibrating or knocking noise correlates with vibrations of entire unit; adjusting leveling legs reduces noise.

Part: Refrigerator leveling legs/frame

Ice buildup blocking moving parts or fan

How to Identify: Noise during fan operation or mechanical movement; visible frost/ice around fan blades.

Part: Evaporator fan / ice maker moving components

Worn motor, fan bearings, or drive gear mechanisms

How to Identify: Persistent grinding or repetitive mechanical noise during operation; fan or motor hard to turn by hand.

Part: Ice maker motor / fan motor / internal gears

Foreign object or ice jam inside ice maker

How to Identify: Noise accompanied by irregular ice ejection or blockages seen when removing ice bin.

Part: Ice maker internal cavity / ejector
