Strong chemical or burning smell coming from the wine cooler.

Safety: Immediately unplug the appliance. Do not continue to operate it until the source of the smell is identified and corrected.

• Inspect rear compartment: Look for discolored or melted insulation, wiring, or PCB components near the compressor and power module.
• Check main PCB: Remove the control board cover and inspect for burnt components or scorching.
• Examine internal lights and heaters: Ensure the LED module and any door frame heaters are not overheating or melting nearby plastic.
• Replace damaged parts: Install a new Grundig main control board, wiring harness, or other affected components as needed.
• Do not use until repaired: Operating with burnt components is a fire risk; seek professional service if unsure.
