John H Baldwinsville , NY August 09, 2014 Appliance: General Electric Refrigerator TFX20DLB Ge Refrigerator Tfx20dlb: Refrigerator door was binding as it closed; would not close on its own. How to replace Refrigerator Door Cam Riser. I determined that the cam riser had broken into two pieces. Finding the part was easy on the diagram on the website. It arrived less than 24 hours after it was ordered. Top hinge was removed and the door was placed on a set of horses. One bolt was removed from the bottom of the door, the pieces of the broken cam riser were removed and the new one installed. Door was replaced and top hinge rebolted. The door was off for about 5 minutes. I was very pleased with the service of Appliance Parts Pros. 30 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
