Rattling or vibrating noise, especially when the compressor starts or stops.

Safety first: Unplug the refrigerator before adjusting panels or tubing.

Check external causes:

• Remove items from the top of the refrigerator that may vibrate.
• Ensure the refrigerator is not touching the wall or cabinets.

• Tighten panels: Check the rear access panel and any loose screws. Tighten as needed.
• Secure tubing: Gently bend or pad refrigerant lines that are touching each other or the cabinet to prevent rattling. Use foam sleeves or clips.
• Level the unit: Adjust leveling legs so the refrigerator is stable and slightly tilted back.

Note: After adjustments, restore power and listen for improvement.
