2. Remove and Inspect the Basket and Tray
- Take out the basket and tray carefully.
- Check for visible grease, food debris, or burnt residue.
- Look for any food particles stuck to the heating element or sides.
3. Clean the Basket and Heating Area Thoroughly
- Wash the basket, tray, and any removable parts with warm, soapy water.
- Use a non-abrasive sponge or cloth to remove grease and residue.
- For stubborn spots, soak parts in warm soapy water for 10-15 minutes.
- Wipe the interior, especially the heating element, with a damp cloth carefully.
4. Check and Replace Liners and Use Proper Accessories
If you use disposable liners or oven mesh racks, ensure they are placed correctly and used as recommended. Avoid placing liners during preheating, and always have enough food on liners to prevent them from flying up and touching the heating element, which can cause smoke.
5. Prevent Future Smoking
- Regularly clean your air fryer after each use.
- Avoid overfilling the basket; leave space for hot air to circulate.
- Use compatible accessories like the ALJ 3PCS Air Fryer Oven Mesh Rack to promote even cooking and reduce residue buildup.
If smoking persists, consider checking the heating element for damage or grease accumulation that might need professional servicing.
