Clean Your Air Fryer Thoroughly
- Unplug the appliance and allow it to cool completely.
- Remove the basket and any accessories, then wash with warm, soapy water. Use a non-abrasive sponge.
- Wipe down the interior with a damp cloth to remove grease or food particles.
- Dry all parts completely before reassembling.
Check and Use Proper Liners
- If using liners, ensure they are heat-resistant and placed properly, avoiding preheating with liners in place.
- Never place liners during preheat—this can trap heat, causing smoke.
- Use liners like the Cosori Air Fryer Liners or similar, ensuring they are not overflowing and are placed flat in the basket.
Adjust Cooking Practices
- Reduce the amount of oil used in recipes to prevent excess drips that can cause smoking.
- Avoid overfilling the basket; leave space for air circulation.
- Set the temperature to a moderate level (around 350°F) if you notice smoking, then increase gradually.
Perform Preventive Maintenance
- Regularly clean the fan and heating element area using a soft brush or cloth to remove grease buildup.
- Check for any damaged parts or loose screws, and tighten or replace as needed.
- Ensure the air filter (if applicable) is clean and unobstructed.
