A:Answer The temperature range varies depending on the main setting (Air Fry, Broil Bake, Pizza, Reheat, etc.). The default is Air Fry (170-400). The lowest range is in the Dehydrate mode (90-170) The widest range is found in several of the main settings (170-400). Basically, it seems you cannot get the full range of 90 to 400 in any main setting, and you must choose one. There does not seem to be a "Free Style" setting. All degrees in Fahrenheit.
