The Fan Motor is an OEM part for LG refrigerators. It is essential for circulating air throughout the refrigerator and freezer compartments, ensuring that the temperature is evenly distributed and maintained at the set levels. This motor powers the fan that helps to cool the evaporator coils and dissipate heat, which is vital for the appliance's cooling efficiency.

Symptoms of a failing Fan Motor include:

• The refrigerator not cooling adequately
• Unusual noises coming from the refrigerator, such as humming or buzzing
• Ice buildup in the freezer compartment due to poor air circulation
• The refrigerator cycling on and off more frequently

Causes of a bad fan motor can include wear and tear over time, obstructions in the fan blades, or electrical issues such as faulty wiring or a malfunctioning capacitor.

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