This 3 year old Fridgidaire needed 2 new shelves as the plastic frames just split/cracked and almost collapsed...actually ALL of them should be replaced but at $90+ apiece, I've been doing them one at a time; I live in Hawaii, shipping is a killer. The Service Agent was really very nice and a big help, assured me that the shelves had been re-engineered but I didn't see much effect to that being done; side-by-side the plastic edging looked about the same heft as the ones I had repaired. I see here I could have added pictures...wish I had seen this earlier!!
