How do I clean the Ninja Double Stack XL Air Fryer?

What is the Smart Cook System?

Can I cook different foods at different temperatures and times simultaneously?

Does it come with recipes or cooking guides?
Yes, a chef-created Recipe Guide packed with ideas and cooking charts is included in the box to help you get started and make the most of your new appliance.
Troubleshooting
Food is not cooking evenly or crisping properly.
Ensure you are using the crisper plate and/or Double Stack meal racks when cooking on multiple levels. Avoid overcrowding the drawers; layer food appropriately on the racks and ensure there is space for air circulation. For some foods, flipping or shaking mid-cycle can improve results. Check that the recommended cooking temperature and time are being used.
Smart Cook System probe is not registering or stopping cooking.
Ensure the Digital Cooking Probe is fully inserted into the thickest part of the meat or fish, avoiding bone or gristle. Verify that the correct food type and desired cook level (e.g., Medium, Well Done) are selected on the control panel. If the probe is damaged, contact customer support.
One drawer is cooking faster/slower than the other or SYNC function isn't working as expected.
Confirm that both drawers are correctly set to the desired function, temperature, and time. If using SYNC, ensure it is activated after setting both drawers. Differences in food quantity or type can affect cooking times; for best SYNC results, try to cook items with similar cook times or use the recommended pre-programmed settings.
Air fryer produces smoke or unusual odors.
Initial use may produce a slight odor due to manufacturing residues; this is normal and will dissipate. Persistent smoke can indicate grease buildup. Ensure all drawers, crisper plates, and racks are thoroughly cleaned after each use. If cooking high-fat foods, excess fat dripping onto the heating element can cause smoke; ensure crisper plates are in place and consider using foil liners if specified in the recipe.
