ABSTRACT:
A refrigerator door assembly is mounted on a stationary frame of a refrigeration unit and comprises a door frame integrally molded about a thermo-pane in sealing relationship therewith. The door frame is hingedly mounted on the stationary frame of the refrigeration unit by a pair of upper and lower hinge pins. A torsion bar, integrally molded within the door frame and secured to one of the hinge pins, functions to constantly apply a closing force on the door frame to move the door assembly into sealing contact with the stationary frame of the refrigeration unit.
