Step 2: Clean the Basket and Heating Element
- Remove the basket and wash it thoroughly with warm, soapy water. Use a non-abrasive sponge to remove grease and food residues.
- Check the heating element for any grease or food particles. If necessary, gently wipe it with a damp cloth or a soft brush. Avoid soaking or submerging electronic parts.
Step 3: Inspect for Grease and Food Residues
Look for visible grease or food debris on the basket, tray, or around the heating element. Accumulated residues can vaporize and cause smoke during cooking.
Step 4: Use Proper Liners and Avoid Overfilling
- Place a disposable liner, such as the Cosori Air Fryer Liners, to catch drips and grease, reducing smoke risk. Ensure not to preheat with the liner in place to prevent it from flying up.
- Fill the basket appropriately—do not overfill—allowing hot air to circulate freely for even cooking and reducing smoke formation.
Step 5: Perform a Test Run and Monitor
After cleaning and adjusting, run the air fryer at a moderate temperature (around 350°F) for 10 minutes without food. Observe for smoke or unusual smells. If smoke persists, further inspection or professional repair may be needed.
