Abstract
A cooking appliance includes an oven cavity accessed through first and second French-style doors that are connected to the appliance through a door linkage system. The door linkage system establishes a particular timing of door openings and closings to minimize potential wear of a door gasket. That is, each of the doors has an associated gasket for use in sealing the oven cavity when the doors are closed. One of the doors is provided with an annular gasket, while the other door essentially incorporates a less that fully annular, preferably 3-sided or a three-quarter gasket. With this arrangement, each of the gaskets has three sides adapted to seal against a cabinet shell portion of the appliance, while the fourth side of the first gasket is adapted to seal against an extension provided on the other door.
