Burning smell or electrical odor coming from the wine cooler.

Safety (critical): Immediately unplug the unit if you smell burning or see smoke. Do not continue to operate the cooler until the source is identified and repaired.

Steps:

• Visual inspection: With the unit unplugged and cooled, remove the rear panel and inspect the compressor area, wiring, and control board for burnt insulation, melted plastic, or discoloration.
• Check start relay and overload: Remove these components from the compressor and inspect for burn marks or melted housing. Replace if damaged.
• Inspect wiring harness: Look for loose or overheated connections, especially at the compressor, fans, and control board. Repair or replace damaged wiring.
• Examine control board: Check for burnt components or traces. Replace the board if any damage is found.

Warning: If you cannot locate the source of the smell or if damage is extensive, contact a professional technician. Do not use the unit until it is deemed safe.
