Hi dsisk10...
Your problem is a faulty water solinoid inlet valve.
You have either two or a combo water solinoid inlet valve.
If you have a seperate water solinoid valve that controls the water to the ice maker and a seperate solinoid to control the water to the water dispenser, then the one that controls the water to the ice maker is faulty and is in need of replacement.
If it is a two in one combination solinoid valve then you will have to replace it.
If your really lucky, sometimes when you pull the old solinoid valve out it will have some trash blocking the water inlet screen, if so you can remove the trash and the valve will work again, but most of the time the valve will have to be replaced.
The water valves are most of the time located around the motor and fan area, and can be gotten to by the removal of the bottom panel from the refrigerator.
After you remove the solinoid, get an old motor cord, extesion cord with a electrical plug on one end and bare wires on the other.
Take the two wires from the extension cord and wire them together with the wires from the solinoid valve that you have removed from the refrigerator and making sure you are NOT TOUCHING the wires, plug the cord into a wall socket, the solinoid valve
should click if it is good, if it does not click then replace it as it is faulty.
I will include a link for the parts for your refrigerator...
