Wine cooler makes loud humming or buzzing noise from the rear, especially when the compressor runs.

Safety: Unplug the unit before reaching into the compressor compartment. Metal edges can be sharp.

Steps:

• 1. Level the appliance: Use a spirit level to ensure the wine cooler is level front-to-back and side-to-side. Adjust leveling feet as needed.
• 2. Inspect compressor mounts: Access the rear compartment and check rubber grommets under the compressor. Replace if cracked or missing.
• 3. Secure tubing: Gently move copper lines away from cabinet walls or each other if they are touching and vibrating. Use foam sleeves or clips to prevent contact.
• 4. Check condenser coil: Ensure the condenser is firmly mounted and not rattling against the frame.
• 5. Test noise: Restore power and listen. Make small adjustments until noise is minimized.

Warning: Do not bend refrigerant lines sharply or apply excessive force; this can cause leaks.
