Rattling or vibrating noise, especially when compressor runs.

Safety first: Unplug the refrigerator before bending any tubing or tightening components near electrical parts.

Steps:

• Level the unit: Adjust front leveling legs so the refrigerator is solid and does not rock. Slightly tilting back helps doors close.
• Check rear components: Remove rear panel and gently separate any copper lines touching each other or the cabinet using foam sleeves or zip ties.
• Tighten brackets: Secure any loose condenser coil brackets or compressor mounting bolts (do not overtighten).
• Interior check: Ensure shelves, drawers, and bottle racks are seated properly and not rattling.

Corrective action: After adjustments, restore power and listen for improvement. Persistent vibration may require a technician to inspect internal mounting points.
