David D Windermere , FL May 22, 2016 Appliance: Frigidaire Refrigerator LGHN2844MF0 Frigidaire Refrigerator Lghn2844mf0: Upper shelf rails wore out causing the (upper) shelf to collapse on the bottom when the freezer drawer was opened. How to replace Slide Set (Right And Left). Replace both (L&R) slide rails. One screw each side. The other two 'screws' were permanently fixed so I just slide the sides over the slide keyholes. Piece of cake. 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
