GFSS6KKYCSS GE refrigerator ice maker problem

[fobicboy]

My GE profile refrigerator is not producing ice. The problem is the ice maker is not dispensing water into the molds. I checked and tested the inlet valve by providing an external 120VAC. The valve energized and dispensed water into the ice maker. Later the ice maker harvested the ice but no water was dispensed for the next set of cubes.  I have confirmed the valves work and the water lines are dispensing water.  My question is does the ice maker energize the inlet valve to dispense water or does the main controller?  I am trying to determine whether to replace the ice maker or something else.

Thank you for your support..
