Burning plastic or electrical smell during use, sometimes with slight smoke from vents.

Safety first: Immediately switch off and unplug the air fryer. Do not continue using it until the source of the smell is identified and corrected.

Steps:

• 1. Inspect cavity: Once cooled, remove the basket and check for plastic packaging, utensils, or liners that may have contacted the heater.
• 2. Access heater area: Remove the top cover and inspect the heater, wiring, and nearby plastics for signs of melting or burn marks.
• 3. Tighten electrical connections: Check heater terminals, thermal fuse connections, and terminal blocks. Tighten any loose connections and replace any discolored or charred connectors.
• 4. Check fan operation: Confirm that the fan runs strongly; a failed fan can cause localized overheating of plastics.
• 5. Replace damaged parts: Any melted wiring, connectors, or plastic shrouds must be replaced. Do not tape over burned insulation; use proper high-temperature wire.

Warning: Persistent burning smell indicates a fire risk. If you cannot locate and correct the cause, discontinue use and consult a technician.
