Loose handle 19 cu ft upright freezer, Kenmore, unknown model or year (approx. 1994) Access to screw is blocked by molded shelves on the door's inside. There is no apparent access to the screw to be able to tighten it. Does the door need to be dis-assembled to provide the needed access?

Yes , on most freezers the door inner panel liner needs to be removed , that will sometimes require the removal of the door gasket that may be old to the point where it to needs replacing. then finally you can get to the back side of the door and snug up the screws that hold the handle from the back. usually fine thread screws. be sure to apply loc tite and snug up good , we don't want to do this again any time soon. you can take a chance and try pulling out the handle and cutting the screws and then drill the hole in the handle out to where you see a hole in the side of the handle from the front, then counter sink the hole and use a drill screw or a small toggle bolt to resecure the handle . no real wires or refigeration tubes in the door, so its an option. good luck
