The refrigerator is making a loud rattling or vibrating noise, especially when the compressor is running.

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

Steps:

• Level the unit: Adjust the front leveling legs so the refrigerator is stable and does not rock. A slight rearward tilt helps the doors close.
• Check rear components: Ensure the 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 the rubber grommets remain in place.
• Remove or reposition items on top of the refrigerator that may be vibrating.
