Wine cooler makes a loud humming or buzzing noise while running.

Safety: Unplug the unit before adjusting components or moving it.

Noise reduction steps:

• Level the cooler: Use a spirit level to ensure the cooler is level front-to-back and side-to-side. Adjust the front leveling legs as needed.
• Check for cabinet contact: Ensure the sides or back are not touching walls or cabinets, which can amplify vibration.
• Inspect compressor mounts: Remove the rear panel and check that the compressor mounting bolts and rubber grommets are intact and snug. Replace worn compressor mounting grommets if necessary.
• Examine condenser fan: Spin the fan by hand to check for wobble or blade contact with shrouds. Tighten mounting screws or replace the condenser fan motor if noisy.
