Step 2: Clean the Interior Thoroughly
- Remove the basket and tray from the air fryer.
- Wash these components with warm, soapy water, or place them in the dishwasher if they are dishwasher safe.
- Use a soft brush or cloth to clean any grease or food residues from the heating element and interior surfaces.
- Dry all parts thoroughly before reassembling.
Step 3: Inspect for Damage or Buildup
Check the heating element for signs of damage, such as cracks or burn marks. Look for any food debris or grease that may have accumulated around the heating area or wiring. If you notice damage, contact customer service or a professional repair service.
Step 4: Use Proper Liners and Racks
Using disposable liners like the Cosori Air Fryer Liners or oven racks such as the ALJ 3PCS Mesh Rack can help prevent grease and food particles from sticking to the basket, reducing smoke. Always ensure liners are placed correctly and do not obstruct airflow.
Step 5: Check for Vent Blockages and Prevent Overcrowding
Ensure the air intake and exhaust vents are free of obstructions. Do not overload the basket, as excess food or grease can cause smoke. Shake or stir food mid-cycle if applicable, to promote even cooking and reduce buildup.
