Abstract
A method for controlling the duration of a self-cleaning operation in an oven responsive to the oven usage. The oven includes a cooking chamber, a heating device for supplying heat into the cooking chamber, an exhaust outlet from the cooking chamber leading to atmosphere, and a heat control device for controlling the heating device for baking, broiling and self-cleaning cycles. The method of controlling the duration includes the steps of maintaining a count at the heat control device of the length of oven operation time performed since a last self-cleaning cycle, accepting an input at the heat control device to begin a self-cleaning operation, and controlling the heating device to heat the oven cavity for a time period based upon the length of oven operation time performed since a last self-cleaning cycle.
