Plastic parts wear out like clock work every six months.

I removed the top refrigerator side hinge screws. The door came right off. Slipped in the lower hinge pin.. Unscrewed the natural door closer and replaced. Reinstalled the door. It is unfortunate that these parts are plastic. They wear out way too soon. No, the door is not over weighted. If you have no weight in the door the plastic shelves will hinder the door closing. Putting stuff on the shelves makes them take their proper form.
