Clean the Air Fryer Thoroughly
- Unplug the air fryer and let it cool completely.
- Remove the basket and any accessories, such as racks or liners.
- Use warm, soapy water and a non-abrasive sponge or cloth to clean the basket, the tray, and the heating element area.
- Pay special attention to the heating element, removing any stuck-on grease or food particles.
- Dry all parts thoroughly before reassembling.
Check & Improve Usage Practices
Always preheat the air fryer empty for about 3 minutes before adding food to prevent excess oil from burning. Avoid overfilling the basket, as excess grease and food debris can cause smoke. Use recommended accessories like mesh racks or liners properly, ensuring they do not cover the heating element.
Proper Liners & Accessories
- Do not place liners during preheating to prevent them from flying up and touching the heating element.
- Ensure liners are food-grade and fit well to avoid trapping grease or food residue beneath.
- Use accessories like the ALJ 3PCS Air Fryer Oven Mesh Rack to promote even airflow and reduce residue buildup.
Additional Tips & Warnings
Regular maintenance and cleaning are key to preventing smoking. Always follow manufacturer instructions for cleaning and accessories. Be cautious with liners; improper use can obstruct airflow or cause fires. If smoking persists after cleaning, contact COSORI customer support for further assistance.
