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

Safety: Unplug the unit before tightening internal components.

Steps:

• Level the unit: Use a bubble level and adjust the leveling legs so the cooler is stable and does not rock.
• Rearrange bottles: Ensure bottles are not pressing against the interior walls or each other in a way that amplifies vibration.
• Tighten panels: Check interior and rear panels for loose screws. Tighten any that are rattling.
• Secure tubing: Inspect refrigerant lines and wiring harnesses at the back. Use foam or clips to prevent them from touching each other or the cabinet.
