5040JA2004A Genuine OEM LG Refrigerator Motor Damper Grommet (Rear)
The 5040JA2004A is a genuine LG OEM rubber motor damper grommet for LG and select Kenmore refrigerators. This small rubber component mounts and isolates a fan motor from the surrounding bracket, cushioning it against vibration as the motor runs. This is the rear-position grommet; LG refrigerators typically use more than one grommet to support a fan motor from multiple points.
Made of rubber, this grommet naturally degrades over years of exposure to cold temperatures and constant vibration, eventually cracking, hardening, or losing its cushioning shape. Once it fails, the motor it supports is no longer properly isolated, and the metal motor bracket can end up in direct contact with the surrounding housing. A worn or failed grommet typically shows up as new or worsening rattling, buzzing, or vibration noise coming from the back of the refrigerator, especially noticeable when the fan motor is running. It directly replaces 5040JA2004B, 1268010, AP4635690, AH3526229, EA3526229, PS3526229, EAP3526229, and PD00027884.

Installation Notes
Frequently Asked Questions
My refrigerator has developed a rattling noise from the back. Is this the grommet?
Yes, this is a common cause of exactly that symptom. Once the rubber grommet cracks, hardens, or loses its cushioning shape, the fan motor's mounting bracket is no longer properly isolated and can vibrate directly against the surrounding housing, producing a rattling or buzzing noise — especially noticeable whenever the fan motor is actively running.
Is this for the evaporator fan motor or the condenser fan motor?
Sources describe this grommet's application somewhat differently depending on the specific refrigerator model — some reference it as supporting the evaporator fan motor, others the condenser fan motor. In practice, this reflects that LG uses the same grommet design for fan motor mounting in more than one location depending on the model. Confirm your full model number against the compatibility list, or check your appliance's parts diagram, to be certain which motor this grommet supports on your specific unit.
Do I need any tools to replace this?
The grommet itself is tool-free — it simply presses into place around the motor mounting post. You will likely need a screwdriver to remove whatever panel is covering the area where the motor and grommet are located, but the grommet swap itself requires no tools.
Is this an OEM or aftermarket part?
This is a genuine OEM part, manufactured by LG to factory specifications — guaranteed fit, materials, and performance. It matches the original rubber compound and mounting fit of the motor damper grommet originally installed in your refrigerator.
