Abstract
An oven temperature control system for an oven cell having a top heating element with two separate heating conductors in a top portion of the oven cell, a bottom heating element with two separate heating conductors in a bottom portion of the oven cell, and a convection heating element and fan. A control separately controls the on and off operations of each of the heating elements and the convection fan based on a selected mode of cooking operation and a selected temperature for cooking. A plurality of temperature sensors are positioned at different locations in the oven cell and operatively connected to the control. The control determines the selected temperature for cooking to be maintained in the oven cell by averaging selected temperatures sensed by the plurality of temperature sensors in predetermined proportions based on the selected mode of cooking operation.
