Whirlpool GD5NHAXMB00 The 2 solenoids on the back of the unit that split the water to the door and the ice maker

But you still have not verified that the hose is not kinked from the internal T where the water splits between the front water and ice maker. When you said you removed the solenoid, the water should have been pouring out. Seems to me a blockage between the T and the solenoid.

Refrigerators use multiple solenoid valves to direct the water to the correct location. There could be a problem with the solenoid valve that controls the water to the ice maker or it could be maker itself not calling for water.

Ice not being dumped out because the heating element designed to slightly melt ice so arms can push it out is non functional and needs replacement. Cheaper and better to replace entire unit at nominal cost.

First check to see if the ice maker is operating. you can take the face plate off and observe if the gears are turning. The next thing to check is the water solenoid. This operates after the ice maker rotates to a certain degree, pushing on a micro switch that sends power to the solenoid (valve) that opens and allows water to flow into the ice maker basin If this solenoid is working you will hear a loud click. Next, check to see if the water in the inflow pipe is not frozen, by disconnecting the refrigerator AC power. Get a hair dryer and play the heat output onto a small plastic pipe that dumps into the back of the ice maker. This pipe sometimes becomes frozen with water ice and will not allow the water to flow into the ice maker. Mine has done this twice over the 12 tears I have had the refrigerator.

Hia and wl;ecome to FixYa, I am Kelly.
We really need a make and model number to provide you with specific unit applicable information but.... in general, here goes:
1. Ice makers must have a freezer temp below 16 Deg F. If there is an airflow problem in the freezer caused by a fan or ice build up the ice maker will no longer make ice.
2. The ice maker has a thermostat that controls the harvest and fill cycle. If the thermostat fails it will stop making ice.
3. There is a water valve in the back of the unit that has TWO electric solenoids on it. One for water in door and one for ice. If a solenoid fails it will stop providing water to the applicable function. I.e water in door or ice. You can briefly remove the fiberboard back cover to gain access to the water valve. Then switch the installed terminal connection between solenoids. Left to right or front to back depending on how it is mounted. Then try the water in door. If water flows to the ice maker when water in door switch is actuated then the solenoid for making ice is good and the probem is with the icemaker. (Reconect wires in original positions.)

Note that anytime you remove power from the unit you must wait 10 - 15 mintues before re-applying power so the coolant system can stabilze. Other wise the compressor will not start.

Here is a web link that will help most people troubleshoot ice maker problems:

The link above is pretty good.
There is a 48 page job aid also for whirlpool in door ice that is also a big help:

This should help you find out why it is not making ice.

Thanks for choosing FixYa,

You have a dual solenoid water valve. Blue for the water and red for the ice-maker. It located in the rear lower part of the frig. The water solenoid needs replacing that will solve your problem. BB

Yes, the ice maker controls the water valve. First check that there is water in the ice maker trays. If there is your valve is not the problem. If not, loosen the fitting on the water line that leads to the water solenoid valve. If you do not find water, check your manual valve that taps into the main water line. If you do have water, it may be that the water inlet above and behind your ice maker is frozen. You can thaw it out with a hair dryer and see if that is the problem. If this model dispenses water through the door, you can find the water solenoid valve behind the unit near the floor and reverse the two plugs on the solenoids. Place a paper towel in the water inlet tube that channels the water into your ice maker. Close the coor and press the water dispenser for 3 seconds. Open the door and see if the paper towel is wet. If it is, the water solenoid is fine. You can also remove the front of the ice maker and put an insulated jumper wire between the T and H test points to see if the unit ice maker will go through its cycle.

Your ice maker has an automatic shutoff. The ice maker sensor passes a beam from one freezer wall to the other, automatically stopping ice production when the storage bin is full. When you open the freezer door, you should see a red light on the top right freezer wall.When the freezer door is open or the ice storage bin is removed, the sensor cover or "flipper door" on the left wall of the freezer stops the ice maker from producing ice by blocking this sensor, When the beam is blocked, the red light on the right will blink twice. This is normal operation. as for the blink twice and pause I'm still checking on that. Make sure the water flow is coming from the solenoid valve located on back and bottom of refrigerator to the ice maker. Check the solenoid to see if the magnetic field is pulling the internal plunger open when ice maker ask for water. That can be checked with a multi meter at the wireing going to the solenoid and if the ice optics are telling the tray to fill voltage should be present. Insure that water supply is not restricted before it comes to the solenoid , like a bent line or clogged piercing valve.  Check that an ice cube is not jammed in the ejector arm of the ice maker. Remove jammed ice from the ejector arm using only a plastic utensil so the ice maker is not damaged. Call toll free in USA and a trained consultant will be happy to assist you. 1-866-698-2538

POSSIBLE YOU HAVE 2 SEPERATE WATER SOLENOIDS. THE SOLENOID FOR THE ICE MACHINE HAS A STRAINER AND ORFICE JUST INSIDE THE INLET SIDE OF THE WATER CONNECTION. CAREFULLY REMOVE THE ASSEMBLY AND CLEAN-IT. YOU CAN CHECK IF ICE MACHINE SOLENOID HAS POWER BY TAKING A METAL BUTTER KNIFE AND HOLDING IT JUST ABOVE THE COIL ... THE MAGNETIC FORCE SHOULD BE FELT TUGGING THE BLADE DOWN. LOSSEN THE NUT ON THE OUT-LRT SIDE OF THE ICE MACH. SOLENOID AND SEE IF YOU HAVE WATER ...
