Possible Causes

Loose compressor mounting bolts, Worn rubber grommets, Internal compressor mechanical wear, Refrigerant lines hitting cabinet during start/stop

How to Fix / Troubleshooting

Safety: Unplug the refrigerator before adjusting compressor mounts. The compressor can be hot.

Steps:

  • 1. Access compressor: Remove the rear lower cover.
  • 2. Check mounts: Ensure the compressor mounting bolts are snug but not overtightened. Replace worn rubber grommets if visibly deteriorated.
  • 3. Adjust tubing: Gently bend refrigerant lines away from the cabinet or each other if they are touching and causing noise during vibration.
  • 4. Internal noise: If the knocking is clearly from inside the compressor and persists, the compressor may be failing and should be evaluated by a professional.
