are all these refrigerators setup to accept an ice maker?

Most refrigerator are set up to install an ice maker. If you provide me with your model number I can check and see for you. Also, look inside your freezer where the ice maker would go. on the back panel you may see a small cover that can be removed. Here you should see a spot for the ice maker fill tube and wire harness. There are also going to be 2 holes in the side wall to put screws to mount the ice maker. If so your refrigerator is set up for an ice maker. With the model number I can look up the ice maker kit you will need.
