Fridge door stopped closing.

The plastic door closing cams had broken after 17 years of use. It was tricky figuring out how the new cams fit as the old ones had disintegrated. Also you need 2 cams - not one. I first ordered only one. A detailed parts diagram would have helped. First unscrew the top door mount cover and then the top door mount. The fridge door then lifts up and off the lower door mount. Next is the hardest part - drilling off the old pop rivet which held the lower cam. The lower door mount had to be removed to get at the underneath of the pop rivet, and a bench vise was handy to hold it as I drilled off the old rivet. Then you need small stainless steel nut and bolt and split washer or lock nut to replace the rivet. Next unscrew the old upper cam from the underneath of the fridge door and replace. The large hole in the cam goes through the door hinge pins. The two plastic cams should interlock in a way that makes the door swing close. Anyway, now the door works fine.
