The method of molding a refrigerator door by preheating a pair of plastic sheets and thence placing the first sheet and the second sheet on a lower female mold and on a plug assist female mold, respectively. The preheated sheet in the lower mold has a full vacuum drawn thereon to mold such first sheet into the final form of the front door panel. A partial vacuum is drawn on the second sheet to partially form the plastic sheet into the configuration of the final form of the inner door panel and thence the preformed second sheet is transferred to an upper male mold by drawing a full vacuum on the upper mold to effect such transfer and molding to a finished inner door configuration. The two panels thence have their outer perimeters fusion bonded to form a closed chamber that is filled with foam insulation after cooling of the formed and joined door panels.
