Plus, a third heating element surrounds the fan and delivers consistent heat. This model also features the TrueTemp system that manages oven temperatures to ensure accurate and consistent heating, a SmartSet oven control and an hidden bake element. The cleaning will be easier thanks to the automatic self-clean oven door lock and heavy duty self-clean oven racks.
