Abstract
A method and a cooking appliance has a pyrolytic cleaning control in which multiple stages permit volatile residue to be incinerated before inducing air current flow that can complete the cleaning process throughout the oven housing. The oven combines cooking energy sources, including convection current heating and preferably, jet impingement heating, whose blowers are disabled during a first stage of pyrolytic cleaning to avoid uncontrolled ignitions within the appliance. The second stage of the pyrolytic cleaning process induces current flow to distribute pyrolytically heated air throughout the housing and complete the cleaning process in the apparatus.
