Most of the time was sent to removing and replacing door shelves. Pry off upper hinge cover. Easy, it's only plastic. Remove 3 fastener from top hinge and remove hinge. Lift door off lower hinge. Lay door down on table let handle hang over edge. Remove door closer attach fastener. Remove and replace door closer. Pry lower hinge up and out. Tap new lower hing pin into place. Replace door, upper hinge and hinge cover. Had to replace Door Closer and Hing Pin together; both were worn and needed replacing.
