There are two heavy-duty self-clean oven racks making this a fully self cleaning oven. The PreciseAir convection system features an innovative fan which reverses direction for optimal air and heat circulation giving precise baking, cooking and roasting results. An added panel on the bottom of the oven hides the lower element for a cleaner appearance as well as protection of the element. The TrueTemp system delivers even heat distribution and gives maximum control over the oven temperature giving better and more predictable baking and broiling results, while the easy to use QuickSet V oven controls allow precise cooking temperatures. Oven cooking modes include convection bake and roast, with additional features including convection conversion, delay bake and variable broil. The smoothtop surface has two 6" radiant burners, as well as one 5"/8" and one 9"/12" elements which vary depending on the size of pan being used. There is also a 6" warming zone.
