Rattling or clanking noise when the compressor starts or stops.

Safety: Unplug the cooler before adjusting components at the rear.

• Secure shelves: Ensure all shelves and racks are properly seated and not overloaded.
• Inspect tubing: At the rear, gently move copper lines away from each other and from the cabinet walls, adding foam sleeves or clips where needed.
• Check condenser mounting: Tighten any loose screws or brackets holding the condenser coil.
• Compressor mounts: Inspect rubber grommets under the compressor. If deteriorated, have them replaced by a technician.
