Wine cooler makes loud humming or buzzing noise from the rear, louder than normal operation.

Safety: Unplug the appliance before touching any moving parts or removing panels.

Steps to reduce noise:

• Level the unit: Adjust the front leveling feet so the cabinet is stable and does not rock. An unlevel unit can amplify vibration noise.
• Access rear compartment: Remove the rear lower panel and observe the condenser fan while the unit is running (briefly reconnect power for this test). Ensure the fan blade is not rubbing against the shroud or wires; reposition as needed.
• Check fan motor: If the fan is noisy even when unobstructed, replace the condenser fan motor.
• Inspect compressor mounts: Check the rubber grommets under the compressor. Replace any that are cracked or missing to reduce transmitted vibration.

Note: Some compressor hum is normal, but sudden increases in noise may indicate impending component failure.
