Step 2: Clean the Basket and Interior
- Remove the basket and accessories, such as racks or liners, and wash them with warm, soapy water. Use a non-abrasive sponge to remove grease and food residue.
- Wipe down the interior walls with a damp cloth. Pay special attention to the heating element and fan area, removing any stuck-on grease or crumbs.
Step 3: Check and Clear Vents and Fans
Use a soft brush or compressed air to clear any dust or debris from vents and the fan. Blockages can cause overheating and smoke, so ensure these areas are free of obstructions.
Step 4: Inspect and Replace Accessories
If you’re using liners or racks, ensure they are appropriate for high temperatures and placed correctly. Avoid placing liners in the basket during preheating or without food to prevent smoldering or fire hazards.
Step 5: Test Run and Monitor
After cleaning and inspection, plug in and turn on the air fryer. Run it at a low temperature for 10 minutes to see if smoking persists. Keep an eye on it during this test to catch any issues early.
