ABSTRACT:
A metal shield is for an oven which has an interior, a door opening which is surrounded by a door frame, and a door for extending across the door opening. The door is for making sealing contact with the door frame. The metal shield includes a plurality of generally parallel elongated metal members which combine to form an array of elongated metal members substantially lying within a plane. The array of elongated metal members is disposed within the interior of the oven inwardly of the door frame and inwardly of the door when the door is in sealing contact with the door frame. The array of elongated metal members extends generally transversely to the interior of the oven with the plane being generally parallel to the door frame.
