Wine cooler makes a rattling or clanking noise when the compressor starts or stops.

Safety: Unplug the unit before tightening any hardware.

• Secure internal items: Rearrange bottles and racks so they are not touching the cabinet walls or each other excessively. Use rack dividers if provided.
• Check compressor mounts: Access the rear compartment and verify that the compressor mounting bolts and rubber grommets are intact. Tighten loose bolts gently.
• Inspect condenser coil: Ensure the condenser coil is firmly attached to its brackets and not free to vibrate. Tighten screws or add foam padding where needed.
• Panel resonance: Press on the rear panel while the unit is running to see if the noise changes. If so, add additional screws or vibration-damping material.

If the noise is clearly internal to the compressor and worsening, consult a professional for compressor evaluation.
