Plastic cam at the bottom of the door disintegrated so door won't shut

1.Emptied the stuff from inside of the fridge door.
2.Using a phillips screw driver I removed the plastic cover over the top hinge.
3. Using a small ring spanner I removed the two bolts holding the top hinge (pin), removed the hinge and lifted the door off the bottom pin.
4.Using the same spanner I removed the bottom hinge containing the broken plastic cam.
5.Replaced the broken hinge with the new one and put a little grease on the hinge pin.
6.Placed the new plastic cam on the hinge pin and refitted the door.
7.Replaced the top hinge and plastic hinge cap, Job Done!

A couple of points a) When your plastic cam needs replacing, always buy the hinge pin & plastic cam. The pin has a plastic cam welded to it and as this is the partner of the plastic cam it will also be worn so you should replace them as a pair.
b) You will spend more time cleaning the 'out of the way' parts of the fridge than actually carrying out the repair.

My fridge is now as good as new.
