Loud humming, rattling, or vibrating noise during operation.

Safety: Unplug the cooler before tightening any components at the rear.

Steps:

• Level the unit: Use a spirit level and adjust the front leveling feet so the Auseo wine cooler is stable and does not rock.
• Rearrange bottles: Ensure bottles are not touching the rear wall or each other in a way that can cause rattling. Use shelf spacers if provided.
• Check shelves: Make sure shelves are fully seated in their tracks and not loose.
• Inspect compressor mounts: Remove the rear panel and verify that the compressor mounting grommets and brackets are intact and tight.
• Check condenser fan: Ensure the fan blades are not hitting wiring or shrouds. Tighten any loose screws and secure wiring away from moving parts.

Note: Some low-level humming is normal, but sudden changes in noise level may indicate a developing fault.
