Air fryer emits a burning smell or smoke (not just initial new-appliance odor).

Safety first: Turn off and unplug immediately. If flames are present, keep the basket closed and unplug; do not open until flames subside. Do not use water on grease fires.

Steps:

• Cool down: Allow the unit to cool completely before inspection.
• Deep clean: Remove basket and pan. Thoroughly clean the pan, basket, and interior surfaces with degreaser suitable for kitchen appliances. Gently clean around the heater guard.
• Remove foreign objects: Ensure no baking paper, plastic, or cardboard remains in the cavity or on the heater.
• Check temperature control: If overheating recurs despite cleaning, test the NTC sensor and thermal cut-out. Replace faulty components.
• Test run: Run the unit empty at a moderate temperature for 10–15 minutes to burn off residual grease, monitoring for smoke.

Warning: Persistent burning smell after cleaning indicates a potential control or wiring fault; discontinue use and seek service.
