Loose green wire inside cavity

Loose green wire inside cavity

I have a Kenmore Elite Microwave and it is hard to open due to the Sagging. The top round portion of the hinge pivoting on the round piece like a rivot is worn flat to the middle of the round piece on one side and has actually started to bend due to the weight of the door. I do not see a way to remove that piece from the upper portion of the door
