Strong chemical or burning smell coming from the wine cooler.

Safety: Immediately unplug the unit if you smell burning plastic or insulation. Do not continue to operate until inspected.

Steps:

• Visual inspection: With the unit unplugged and cooled, remove the rear panel and inspect the compressor area, control board, and wiring for burn marks, melted insulation, or discoloration.
• Check start relay: Remove the compressor start device and smell it; a strong burnt odor or visible charring indicates failure. Replace with the correct part.
• Inspect control board: Look for burnt components or cracked solder joints. Replace the main control board if any damage is found.
• Clean condenser: If the smell is more like hot dust and the unit has been unused for a long time, clean the condenser coil thoroughly and monitor for recurrence.
• Do not ignore: If you cannot identify the source or the smell returns quickly, discontinue use and contact a professional technician.
