Wine cooler makes loud humming, buzzing, or rattling noises during operation.

Safety: Unplug the unit before adjusting components or touching moving parts.

Steps:

• Level the unit: Use a level and adjust the front leveling legs so the cabinet is stable and does not rock.
• Check rear components: Remove the rear panel and inspect the condenser fan, shroud, and compressor mounts. Tighten any loose screws.
• Isolate tubing: If copper lines are touching the cabinet or each other, gently bend them away and insert foam or rubber spacers to prevent contact.
• Inspect compressor mounts: Replace worn or missing rubber grommets under the compressor to reduce vibration.
• Fan noise: If the fan motor is noisy or the blade is damaged, replace the condenser or evaporator fan motor as appropriate.
