Wine cooler makes loud knocking or rattling noises when the compressor starts or stops.

Safety: Unplug the unit before adjusting any components in the compressor compartment.

Steps to address rattling:

• Check rear panel: Ensure the rear service panel is securely fastened with all screws in place.
• Inspect compressor mounts: Verify that the compressor is firmly held by its mounting brackets and rubber grommets. Tighten loose bolts carefully without over-tightening.
• Secure tubing: Look for copper refrigerant lines that may be touching each other or the cabinet. Gently bend them apart slightly and insert foam or rubber spacers to prevent contact.
• Test operation: Restore power and listen during compressor start/stop to confirm noise reduction.

Warning: Do not kink or sharply bend refrigerant lines; this can cause leaks or restrictions.
