Brian B Saddle Brook , NJ April 12, 2022 GE refrigerator nylon cams on the lower hinge were worn out. I had to take the upper hinge off and remove the door. The plastic cam goes on the bottom of the door. The hinge has the same piece riveted to it. Didn't take very long. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
