LG Refrigerator Damper,Motor Support

The LG Refrigerator Motor Support Damper (Part Number: 5040JA2004B) is an authentic original equipment manufacturer (OEM) replacement vibration dampening component designed for LG refrigerators. Fitted around the evaporator fan motor shaft housing, this flexible rubber grommet cushions the motor, absorbing rotational vibration and preventing physical metal-to-plastic contact noise during cooling cycles.

Key Features

• OEM Precision Quality: Manufactured directly by LG to original equipment specifications for exact motor shaft sleeve alignment and snug fitment.

• Vibration-Dampening Rubber: Formulated from high-grade elastomeric rubber engineered to stay pliable and absorb mechanical resonance in freezing conditions.

• Splined Central Hub: Features a star/splined inner bore pattern surrounded by circular raised contact nubs to secure the motor while dampening movement.

Benefits

• Solves loud buzzing, rattling, or humming noises coming from behind the freezer rear wall.

• Holds the evaporator fan motor in proper alignment to prevent the fan blade from hitting the shroud.

• Protects internal fan motor bearings from continuous mechanical stress and impact fatigue.
