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

Safety first: Immediately unplug the appliance if you smell burning. Do not continue to operate until inspected.

Steps to investigate burning smells:

• 1. Visual inspection: With the unit unplugged and cooled, remove the rear panel and inspect the main PCB, wiring, and compressor for signs of burning or melted insulation.
• 2. Check control board: Look for darkened areas, burnt components, or a burnt smell on the PCB. Replace the main control board if damaged.
• 3. Inspect wiring: Follow the harnesses and look for melted or discolored insulation. Replace any damaged wiring and correct the cause (e.g., chafing against metal).
• 4. Dust cleaning: If the smell is mild and there is heavy dust on the condenser or compressor, clean thoroughly and monitor. Persistent strong odor indicates a failing component.
• 5. Professional service: If the compressor itself smells burnt or trips breakers, contact a technician for further diagnosis.
