Chemical or burning plastic smell when the wine cooler is running.

Safety: If you smell burning plastic or see smoke, unplug the unit immediately and do not continue to operate it.

Steps:

• Initial inspection: After unplugging and allowing to cool, remove the rear panel and inspect for melted plastic, burnt wiring, or discolored components.
• Clean condenser: Dust buildup can cause hot smells when first heated. Clean the condenser coil thoroughly.
• Check wiring harnesses: Look for areas where wires may have contacted hot compressor lines or sharp metal edges. Repair or replace damaged wiring.
• Inspect control board: Examine the PCB for burnt components or darkened areas. Replace the board if any damage is found.
• Professional evaluation: If the source of the smell is not obvious, have a qualified technician inspect the unit before using it again.
