Wine cooler makes loud humming or buzzing noise during operation

Safety: Unplug before adjusting components at the rear. Be cautious of hot compressor surfaces.

Steps:

• 1. Level the appliance: Use a spirit level and adjust the front feet so the cooler is stable and does not rock.
• 2. Check rear clearances: Ensure the cooler is not touching the wall or cabinets, which can amplify vibration.
• 3. Inspect compressor mounts: Remove the rear panel and check the rubber grommets under the compressor. Replace if cracked or missing.
• 4. Secure tubing: Gently bend refrigerant lines away from cabinet panels if they are touching and vibrating. Do not kink or sharply bend the tubes.
• 5. Persistent loud hum: If noise remains excessive, the compressor itself may be noisy and require professional evaluation.
