Wine cooler makes a rattling or vibrating noise, especially when the compressor starts.

Safety first: Unplug the cooler before tightening any internal components.

• Leveling: Adjust the front leveling legs so the cabinet is stable and does not rock.
• Rearrange contents: Space bottles so they do not touch each other or the cabinet walls. Ensure shelves are fully seated in their tracks.
• Secure tubing: Remove the rear panel and gently secure any loose refrigerant tubing or the condenser coil with foam or clips to prevent rattling.
• Check fan shrouds: Ensure the evaporator and condenser fan housings are tightly fastened.
