Intermittent rattling or vibrating noise, especially when the compressor starts or stops.

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

Step 1 – Level the appliance:

• Use a spirit level to check side-to-side and front-to-back level.
• Adjust the front leveling legs until the unit is stable and does not rock.

Step 2 – Check internal components:

• Ensure shelves, drawers, and bottle racks are properly seated and not rattling.
• Remove any loose items on top of the refrigerator or touching its sides.

Step 3 – Inspect rear area:

• Look for copper lines or wiring harnesses touching the cabinet; gently reposition and secure with clips or foam.
• Verify compressor mounting bolts are snug but not overtightened.
