Unplugged the frig and defrosted everything to assure it wasn't a frozen line. It wasn't/that didn't fix the problem.
Poured water in the ice maker to see if it would make and dispense ice cubes. Ice cubes were made but not dispensed. Note: I would do this test first next time.
I then determined that at the very least this ice maker was not operational. Theoretically, the water valve and/or wiring could also not be working. So I ordered a new ice maker. Received it in Wasilla, Alaska two days later.
Then I unplugged the frig, unscrewed the screws supporting the ice maker, disconnected the wiring connector, transferred the bottom supporting clip from the old ice maker to the new ice maker, connected the new ice makers electrical connection to the fridge, re-installed the supporting screws, and then plugged the fridge back in. This whole process took 5 to 10 minutes.
I checked the ice tray a couple of hours later and there were ice cubes in the tray. The ice maker was working again.
