During production, an annular flange portion of the inner, refrigerator door liner is joined with an annular sidewall portion of the outer refrigerator door panel at an attachment location positioned inwardly of the annular side wall portion. The inner refrigerator door liner is also formed with either an annular recess or a plurality of spaced recesses in its annular flange portion adjacent the attachment location of the inner refrigerator door liner and the outer refrigerator door panel that is adapted to press-fittingly receive a door gasket. Preferably, the outer refrigerator door panel includes a thickened portion that is formed with a handle defining recess.
