1. How many freezer shelves come with this model?
2. How do you take out/put in a freezer shelf?
3. You show 3 shelves, how do I know which one to purchase?
Answer Hello! You will need to order all 3 shelves called for the freezer section, if they are missing now. The top is p/n W10318953. The middle is p/n W10318952. The bottom is p/n W10318951. You should be able to place the shelves on the support studs attached to the freezer liner. If you are needing the bottom freezer basket the p/n is 2309758. Hope this helps!
