Door had a "hitch" which made a sound when the door was opened.

I emptied the door of food, removed the top hinge by removing two screws. I then lifted the door off the lower hinge. The teflon hinge was just sitting in the bottom bearing. I removed the broken one and replaced it with the new bearing hinge. I didn't need the door stop. I then put the door back on the bottom bearing hinge and returned the top hinge. After replacing the food, the job was done and the "catch" and noise were gone! Success!
