The Ice Maker Cooling Fan Assembly is an OEM replacement part for LG refrigerators. The purpose of this component is to circulate the air that goes into the ice compartment so that the water freezes in the ice maker to make the ice. It also runs intermittently to ensure the ice that has been made remains frozen.

Causes of a bad cooling fan assembly can include failure of the electric motor or fan blade over time due to prolonged use. Bearing wear is also common with extended operation of moving parts like the fan blade.

Symptoms of a bad cooling fan assembly include:

• Inconsistent or infrequent ice production  
• Warm spots developing within the freezer compartment
• Vibrations, rubbing, or grinding noises from the fan motor area
• Inefficient freezing of items stored in the freezer

Replace yours today with this genuine OEM LG cooling fan assembly to restore optimized temperature control. 

This OEM LG part is also compatible with Sears/Kenmore refrigerators.
