DIAGNOSIS A loud mechanical noise indicates a problem with the ice-making mechanism. The primary suspect is the evaporator plate or auger being obstructed by a mineral scale buildup or a foreign object.
FIX Immediately cancel any cycle and power off the unit. Perform a full descaling procedure using a food-grade descaling solution and clean water. Run two complete cleaning cycles as per the unit's cleaning mode instructions to dissolve scale.
IF THAT DIDN'T WORK The noise may originate from the compressor or fan motor. Ensure the unit is on a level, stable surface with at least 4 inches of clearance on all sides for proper ventilation and component alignment.
HEADS UP Continuing to operate with this noise can permanently damage the gear motor that drives the auger, requiring a full component replacement.
