Wine cooler makes loud rattling or vibrating noises, especially when the compressor runs.

Safety: Unplug the unit before bending tubing or tightening compressor mounts.

Steps:

• 1. Level the cabinet: Use a spirit level and adjust the front leveling feet so the cooler is stable and does not rock. Ensure all four corners are supported.
• 2. Isolate from floor: Place vibration-damping pads under the feet if the floor is uneven or resonates.
• 3. Check rear tubing: Inspect the condenser and refrigerant lines at the back. Gently bend any tubes that are touching the cabinet or each other so they have a small clearance.
• 4. Inspect compressor mounts: Ensure the rubber grommets and mounting bolts on the compressor are intact and snug (do not overtighten; the compressor should have some flexibility).
• 5. Secure internal parts: Inside the cabinet, make sure shelves, bottle racks, and the evaporator fan shroud are firmly seated and not rattling.

Note: A low, steady hum is normal; sharp rattles or metallic clanks indicate something is loose or touching.
