This is the second time I have had to replace the crisper covers in my Frigidaire Refrigerator. The cheap plastic frames break easily. The fix was easy because I was able to get the right replacement parts from AppliancePartsPros.com. The website makes it very easy to identify and order the right parts the first time. Once a received the parts, I simply removed the old, broken shelves and replaced them with the new ones. I should probably save the part numbers this time so I have them next time these things break.
