ABSTRACT:
An oven door assembly for hinge mounting on an oven frame, the door having a glass-sealed window aperture and a shutter manually positionable between an open position permitting view of the oven contents through the window and a closed position preventing thermal radiation from the oven through the window and view of the oven contents. Shutter position indicator means governed by the movement of the shutter to and from its closed position cooperates with sensor means on the oven frame to provide an interlock for the oven heating system such that the heating system is prevented from operating when either the shutter or door is not fully closed. The shutter is disposed within an air wash zone formed by spaced door panels in a manner which permits both sides of the shutter to be cooled by convective air flow to thereby minimize heat transfer to the outer panel of the door.
