The inlet valve is a dual valve in one body. One side is for the dispenser and the other is for the ice maker. The ice maker side is not working. However if you want to test you can if you have a volt meter. Follow the ice maker water line down to the inlet valve and disconnect the wire connector on that side of the inlet valve. Set your meter above 120 VAC and insert the probes in that connector.
Follow the instructions below to get the ice maker out. Leave the wire connector connected.

In the picture below is the face plate. You will need to remove that. I know its not exactly the ice maker you have but yours comes off just as pictured.
Strip a small piece of insulated wire an put the ends into the holes marked T and H as pictured below.
Tape the door switch and emitter which is the lever to your left just like it would be if the freezer door was shut. Be sure not to block the invisible beam that goes across.
In a minute the ice maker should begin to cycle. If it does cycle let it turn about a quarter of the way around and remove the wire. AT THIS POINT IT MAY SPARK, then It should then continue on its own. If it cycles which it should go around and watch the volt meter, briefly for about 2 seconds there should be voltage near the end of the ice maker cycle. If so then replace the inlet valve. If not let me know.

The inlet valve is the first part your homes water supply connects to. To replace it UNPLUG THE UNIT. Turn off the water, remove the screws holding it on and pull it out where you can work with it. If you look where the plastic lines go into the valve you will see a white or yellow ring. Press that down in toward the valve while pressing the line in at the same time. Then pull the line out while holding the ring down. Simply push the line in the new valve and give it a light tug to be sure its seated.
Once you get all the water lines changed pull a wire connector off the old valve and push it on the new. Do that one at a time so you do not get them mixed up. Thats it. Plug up the unit and turn everything on and it will all start automatically.
For now turn the ice maker off. Its not good for it to cycle without water, it will cycle way to often.
