Refrigerator door wouldn't close automatically.

Removed the top hinge with a socket and lifted the door off. Removed the bottom hinge from the refrigerator with same sized socket. Used a Dermel to cut out the old rivet holding the old mangled cam. Attached the new cam with a screw, washers and nut. Reattached bottom hinge to the refrigerator. Removed the bracket holding the second cam on the bottom of the door. Replaced the shim and cam. Reinstalled the door. No problems. Just don't make the same mistake I made. You need two cams. They interlock and work together to close the door automatically. The cams are identical. They are just off set by 90 degrees when the door is closed.
