ABSTRACT A cavity and cabinet construction for a microwave oven is provided which utilizes two U-shaped members which are nested together to form the cooking cavity and the cabinet. One member forms the front, bottom and rear panels of the cooking cavity and the cabinet and the other member forms the top panel and side panels of the cavity. The second member is laterally smaller than the first member to provide a chamber within the cabinet for housing the electrical components. The two members are secured together around the front panel by a metal crimping technique which prevents distortion and marking of the front face of the front panel and are joined along a bottom and rear edge by a metal stitching technique to secure the two members together in a radiation leak-proof manner. A U-shaped channel hinge bracket is utilized to provide support for a hinged door, the door having a hinge plate which sandwiches the flange of the front panel between the hinge plate and the hinge bracket. The hinge bracket is secured to the front panel and, at one location, to an adjacent side panel. -27-
