Abstract
Provided is a door for a cooking appliance, such as an oven range, with multiple spaced apart glass panels. An interlocking mechanism promotes a proper installation of the glass panels, and interferes with the installation of the glass panels or with operation of the appliance if at least one of the panels is not properly installed. A switch with a plunger can be installed in the door, which allows the appliance to operate only when a failsafe electrical circuit is closed corresponding to a selected position of the plunger when the door is closed. The plunger is prevented from retaining that selected position if at least one of the glass panels is improperly installed or if a top cap is not properly seated or installed above the glass panels.
