ABSTRACT:
An insulated door for use in a refrigerator having an ice and water through the door dispenser is made by attaching a liner for housing the dispenser on the rear face of the door in line with a front opening. The liner is secured to the door as are the hinge bearings and a tube extends between the liner and the lower hinge bearing for conducting electrical wires and a water tube. The only opening in the liner is at a point to receive ice cubes from the dispenser in the refrigerator and this opening is covered prior to foaming. The door is placed in a foaming fixture which completely enclosed and supports the door and the liner and foam is injected so that the foam, when expanded and hardened, completely covers the rear face of the door. After the door is removed from the foaming fixture, the thin layer of foam at the inlet opening is cut away and the door is completed by adding the liner and the gaskets and other hardware as well as the dispensing unit itself.
