Abstract
A method and apparatus is provided for operating a self cleaning oven wherein the monitoring of exothermic chemical reactions within a catalyst can be used to determine when the combustion of food material is complete, in order to terminate a self cleaning cycle. During a self clean cycle, an oven cavity is heated to and maintained at an oven clean temperature suitable for oven cleaning. A catalyst is disposed within an exhaust passage of an oven cavity and the amount of heat generated within the catalyst is sensed. The self clean cycle is terminated a predetermined time after heat generation within the catalyst ceases.
