No. To pause the unit, simply press the dial, which serves as the START/STOP button.
No. To minimize sticking, spray the air fry basket with cooking spray.
Use the air fry basket in the top rails with the Air Fry and Dehydrate functions to maximize airflow. When cooking foods that may drip, slide the SearPlate into the bottom rails to catch any drippings from hitting the bottom heating elements.
The air fry basket holds up to 4 pounds of food.
Yes. It is important to rotate your food for consistent browning and crispiness. For best results, follow the recipe or cooking chart to see how often you should rotate ingredients while cooking.
Yes. The SearPlate has a nonstick ceramic coating.
The SearPlate can be used in the bottom rails with any cooking function. The SearPlate is multifunctional and can be used as a cookie sheet, baking tray or sheet pan. Note that, for Dual Heat Functions (Sear Crisp, Rapid Bake, Griddle, Fresh Pizza, and Frozen Pizza), it is required to preheat the SearPlate. The SearPlate can also be used in the bottom rails to catch drippings when cooking in the air fry basket or wire rack.
Yes. Parchment paper can be used in the oven the same way that you would use it in your conventional oven. Make sure the parchment paper is not touching the interior side walls or top heating elements.
Yes. Use aluminum foil on the SearPlate or wire rack for easy cleaning after cooking. Make sure the aluminum is not touching the top heating elements. Do not wrap the crumb tray in aluminum foil.

Place the air fry basket and sheet pan on heat-safe surfaces only, and use caution when handling, as they will get hot during cooking. You can place accessories on top of the oven. Use a hot pad or trivet to prevent sliding.
Dishwasher-Safe Accessories but Hand-Wash Recommended:

- Wire Rack
Non-Dishwasher-Safe Accessories:
- Crumb Tray

Yes, but crispiness results may vary.
You can follow traditional recipes and package instructions with the Bake function. When preparing traditional oven recipes using the Air Roast function, lower cook time by 30% and temperature by 25°F.
For Air Roast, Air Fry, and Bake, preheating the sheet pan or accessories is not required but adding ingredients before preheat completes may impact cooking performance. Toast, Bagel, Broil, Reheat and Dehydrate do not have preheat.
Smoking can be cause by few factors:
- There may be grease on the heating elements. Ensure you are placing the sheet pan in the bottom rails when using the air fry basket or wire rack, which will stop food from dropping onto the bottom heating elements.
- Also ensure that no food is directly contacting the top heating elements or the top of the cooking cavity.
- If problem persists, run a Toast cycle on shade 7 with accessories removed; this will burn off any additional grease on the heating elements causing smoke.
- The wrong cooking oil may have been used. Ensure that you are using one of the recommended oils: Canola, Refined Coconut, Avocado, Grapeseed, and Vegetable. Not recommended: Olive Oil, Butter, Margarine.
- The marinade may have been heated for too long. If you are using a marinade, ensure that you are applying it halfway through the cooking cycle; applying it earlier will result in smoking/burning of the marinade.
- The temperature may be set too high for the food getting cooked. Cook any fatty foods at 400°F or lower.
When cooking frozen pizza we recommend to follow box temperature instructions, preheat the sheet pan in bottom rails for even results. Do not use wire rack. Reduce cook time by 30-50% from box instructions. Keep an eye on your food while it’s cooking.
Food cooks faster with Air Roast functions, so for traditional oven recipes, lower the cook time and temperature. We recommend reducing cook time on recommended package instructions by 30% and the temperature by 25°F.
