Chemical or plastic burning smell when the refrigerator is running.

Safety: Immediately unplug the refrigerator if you smell burning plastic or see smoke. Do not continue to operate the appliance.

Steps:

• 1. Visual inspection: With power disconnected, remove the rear cover and inspect the compressor area, wiring, and control board for burnt components or melted insulation.
• 2. Check defrost area: Remove the freezer rear panel and inspect the defrost heater and wiring for signs of overheating or foreign objects touching the heater.
• 3. Replace damaged parts: Any burnt wiring, start relay, or control board must be replaced. Use OEM Ikea-compatible parts and proper high-temperature wiring.
• 4. Do not bypass: Never bypass burnt safety devices or fuses; they are critical for fire prevention.
• 5. Professional service: If you cannot identify the source of the smell, contact a qualified technician before using the refrigerator again.

Warning: Fire risk is serious; do not ignore burning smells.
