Rattling or knocking noise when compressor starts or stops.

Safety first: Unplug the refrigerator before adjusting components at the rear.

• 1. Remove items from top: Take off any objects sitting on top of the refrigerator that may rattle.
• 2. Check leveling: Ensure the refrigerator is level front-to-back and side-to-side using the adjustable legs.
• 3. Inspect compressor mounts: Verify the compressor mounting bolts are snug but not overtightened.
• 4. Adjust tubing: Gently reposition any copper or aluminum lines that are touching each other or the cabinet, adding foam sleeves if necessary.
