An electric double oven having two self-cleaning cavities, one cavity also having microwave capability wherein forced air from a blower repels hot self-clean air from entering the waveguide. A circuit is provided for limiting the temperature of either cavity to approximately 505 DEG F. when the other cavity is above a temperature associated with self-cleaning. The circuit also limits the common microwave cavity to approximately 505 DEG F. when the blower is not functioning so that oven cavity air entering the waveguide will not present a hazard.
