Howard T Jeffersonton , VA August 05, 2020 Appliance: Model FRIGIDAIRE LFHB2751TF3 The roller for the crisper bin had broken off and also broke off a piece of the track. The problem was repaired by replacing the shelf. The frame for the shelf contains the roller track. After installing the 2 roller wheels, I was able to reassemble the shelf and reinstall the unit. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
