Persistent burnt smell from the air fryer even when not visibly smoking.

Safety first: Unplug and cool the unit before cleaning.

• Deep clean: Remove basket and tray. Soak them in warm soapy water and scrub off all residue. Wipe the interior cavity, including the ceiling and corners, with a non-abrasive sponge.
• Clean heater carefully: With a soft brush, gently remove carbonized grease from the heating element. Do not soak or spray water directly on the element.
• Run burn-off cycle: After cleaning, run the air fryer empty at a moderate temperature (e.g., 350°F/175°C) for 10–15 minutes to burn off remaining odors. Ensure good ventilation.
• Inspect for melted parts: Look for any deformed plastic components near the heater. Replace any damaged parts to eliminate ongoing odor.
