Strong chemical or burning smell coming from the rear of the wine cooler.

Safety: Immediately unplug the wine cooler. Do not continue to operate it if a burning smell is present.

Steps:

• Visual inspection: After allowing components to cool, remove the rear panel and inspect the main control board, compressor area, and wiring for burn marks or melted insulation.
• Check start relay: Remove the compressor start relay and overload; replace if there is any sign of melting or charring.
• Inspect wiring harness: Look for wires touching hot surfaces or pinched by panels. Repair or replace damaged sections.
• Replace burnt components: Any visibly burnt board or connector should be replaced, not repaired in place.

Warning: If you cannot identify the source of the smell, or if damage is extensive, contact a professional technician. Do not plug the unit back in until it has been inspected.
