You don't know your model's features and quirks

Cooking with an air fryer is a little more challenging than cooking in a conventional oven since not all air fryers are created equal. If the recipe specifies 12 minutes to bake a batch of cookies at 350 degrees, for instance, you may be quite certain that it will take 12 minutes to bake the cookies as long as your oven is operating properly. But it's different with an air fryer. When you first take your air fryer out of the box, the most crucial thing you can do is read the handbook. Not all air fryers, according to Livestrong, recommend the same cooking times for the same foods.

This is such that what takes 12 minutes in one fryer could take 15 in another, as every manufacturer manufactures their fryer differently. Additionally, keep in mind that some fryers feature bells and whistles that you could overlook if you aren't well-versed in what they can perform. For instance, some models offer a two-basket system that enables you to cook two different items at the same time. Others feature different settings for baking, roasting, and frying. Therefore, you might not be fully utilizing all of your model's capabilities if you don't understand all of its quirks.
