Step 2: Clean the Interior Thoroughly
- Remove all accessories, including the basket, racks, and liners.
- Use warm, soapy water or a damp cloth to wipe down the interior, especially around the heating element and fan.
- Pay special attention to any grease or food residue that may have accumulated, as this can cause smoking when heated.
- Dry all parts completely before reassembling.
Step 3: Check for Residue and Oil Buildup
Inspect the heating element, fan, and the interior walls for any visible grease or food residues. Use a soft brush or cloth to remove stubborn grime. Excess oil can burn and produce smoke during operation.

- Set the temperature to 400°F and run the air fryer for 10-15 minutes.
