I have been asked to pickup this question. From the all information that I have just read above, it points to the water valve. You should replace that.
This is what you have stated that leads to the water valve
"After switching the wires from one valve to the other, No water came out of the dispenser."
It will take 24 hours for the ice maker to run correctly. Do not attempt to force the ice maker to load water.
If you have doubts, you can run that same test above. Switch the wires and see if you now get water thru the dispenser. You should get water either way if the valve is working correctly.
Good luck and let me know how you do.
Every time you post at this question it generates an automatic email to me. So, all you have to do is post back here. I check in a couple of times every day.
The valves are what you do want to test.
Just to check, you ran this test before and the wires clips did fit on the old valve (when you switched them)? Did the new valve look exactly like the old one?
Also, take the hose from the ice maker side off and put another temporary hose to a bucket on it. Let's see that the water comes out of that valve.
You can use some electrical tape to tape the connections on it's only for a quick test to confirm that solenoid for the ice maker is working.
If you don't get the both valves working after you test them, then check the voltage for the wires when you press the dispenser button and if there is any voltage from the ice maker's wires (separately).
I had thought that you had done this test on the original water valve.
Anyway, from what you have stated above -
"I hve run the diagnostics for the optics and according ot the tech sheet, the optics are functioning properly."
The optic switching is ok and the water valve is ok. So, we move to the icemaker to test.
Check the wire connections for the icemake to be certain that they are good.
Click below for what you will need to do further testing. If the optics are good, then you can go to page 5-5 and run the component testing. If you find the problem there, you will likely be replacing the icemaker.

You're welcome and thank you for the "accept". Good work on the fix. If you get a chance to give feedback, I would truly appreciate it. It let's others know the job that we have done.
