The PK956 uses PreciseAir Convection System, delivering even air and heat circulation for superior baking and roasting results. With the Convection Bake/Roast feature, it provides an ideal airflow throughout the oven cavity for even cooking and consistent results. Ensure better baking results while roasting meats faster than a traditional oven. Another great feature is their self-clean heavy duty oven racks which are double coated porcelain enameled racks that no longer require hand cleaning. The Glass Touch Controls features a smooth glass design that is easy to use and clean while adding even more to the sophisticated style to your kitchen.
