Product review (5 stars): This is what you need to fix the hinge!
If your fridge door makes a sort of bumping noise as it opens and closes, check the bottom hinge and see if there are black pieces of plastic on the floor, or if there looks like a plastic gasket is chipped or broken. Check your fridge model and the closing cam model for your fridge. This is the second closing cam I've replaced (one on each door). It's not that difficult. Instructions for GE products are usually are online. There's a thin, matching gasket that you need to replace at the same time.
