Rattling or clanking noise when the compressor starts or stops.

Safety: Unplug the cooler before tightening any hardware.

• Secure shelves and bottles: Rearrange bottles so they are not touching the cabinet walls or each other loosely.
• Check internal panels: Ensure interior panels and shelf supports are fully seated.
• Inspect rear components: Tighten any loose screws on the condenser coil brackets, fan shroud, and compressor mounting plate.
• Test: Plug the unit back in and listen during compressor start/stop to confirm the noise is reduced.
