Abstract

A method for controlling the operation of an oven during preheating wherein the oven includes an oven cavity having an interior with at least one heating element for raising the temperature within the oven cavity and a temperature sensor provided for sensing the temperature within the oven cavity. The method of the present invention includes the steps of sensing the temperature within the oven cavity a plurality of times during the preheating period of the oven cycle, calculating the temperature rise within the oven cavity during the preheating period, and cycling the at least one heating element on and off during the preheating period such that the temperature rise within the oven cavity during the preheating period is controlled to match a predetermined temperature rise slope.
