Abstract
An oven and a method for controlling the ambient temperature in an oven comprising a baking cavity that is preheated with respect to a user-selected temperature set point. The baking cavity can include a rack for supporting a pan that conceptually divides the cavity into an upper heating region and a lower heating region. A broil heating element and corresponding broil temperature sensor are disposed in the upper heating region of the baking cavity. A bake heating element and corresponding bake heating sensor are disposed in the lower heating region of the baking cavity. A controlled is provided to control the activation of the broil and bake heating elements in response to the sensed temperature of the upper and lower heating regions to maintain the entire oven at a temperature substantially equal to a target temperature set point, which is determined based on the user-selected temperature set point.
