Refrigerator making loud rattling or vibrating noise, especially when compressor runs.

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

Steps:

• Level the unit: Adjust front leveling legs so the refrigerator is solid and does not rock. Slight rearward tilt helps doors close.
• Check rear components: Ensure condenser coils and refrigerant lines are not touching each other or the cabinet. Gently bend or pad them to prevent contact.
• Inspect compressor mounts: Tighten any loose mounting hardware while ensuring rubber grommets remain in place.
• Remove or reposition items on top of the refrigerator that may vibrate.
