Door closing cam (made of Plastic) just wore out with age and broke in half

Took the door contents out and put them on the counter, took the door off the hinges by unscrewing the 2 screws on the top of the Fridge and lifting the door off the hinge onthe bottom. Then laid down the Fridge on the kitchen floor and replaced the Door Closing Cam, keeping in mind the order of the 3 shims and other things on the bottom of the door. Simple.
