Air fryer emits a strong burning plastic or electrical smell during use.

Safety first: If you see smoke from the housing (not just food), unplug immediately and do not continue using the unit.

• Step 1 – New unit break-in: For a new Ninja air fryer, run it empty at 400°F (200°C) for 15–20 minutes with good ventilation. A mild odor may be normal initially.
• Step 2 – Clean thoroughly: Remove the basket and pan and clean them with warm soapy water. Wipe the interior walls and heater guard to remove manufacturing oils or grease.
• Step 3 – Inspect cord and plug: Check for heat discoloration or melting at the plug or cord.
• Step 4 – Internal inspection (advanced): If the smell persists or worsens, remove the housing and inspect wiring, the control board, and the motor for signs of melting, charring, or burnt components.
• Step 5 – Discontinue use if damage found: Any visible melting or charring requires professional repair or replacement of the affected parts.
