How to replace Refrigerator Glass Shelf (Crisper Cover), Single. I purchased two more freezer shelves. Installation (if you can even call it that) was a simple matter of placing the shelves on the existing molded shelf indentations inside the fridge. Easy, breezy. And now it's so much easier to find things in my freezer! :) Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
