A:
As it says in the owners manual, you can purchase an additional ice maker that is installed in the freezer. I did this and I am very happy with it. The part number for the ice maker is FIB23A. There is a sticker inside the fridge that says the number is FIB23B, but I could not find this model and purchased the 23A and it fits fine. It is easy to install. The hardest part is removing the freezer door and putting it back in. Having a helper for this step is very helpful
The ice maker itself is much larger than the one in the fridge section. It holds at least twice as much ice and the cubes are much bigger. I am very happy with mine.
