rt hand door wouldn't stay closed by itself-door sagged

This door was a problem for 1-2 years before I realized it had dropped about 2 inches. On close examination I saw that the hinge parts had completely broke down.
Had original manual-looked up model # on line under GE appliance and was surprised to find a large complete parts dwg showing parts I needed. Decided I needed the hinge assy.
Removed the door cap on top,replaced hinge assy and remounted door in reverse.--Works like new.
