I was getting 120 at the valve when the ice maker cycled.
How did you check the inlet valve? Volt meter at the wires going to it? They can be sending power to the inlet valve, but if the valve is not making up inside, it cannot work. If you still have the valve, take an ohm meter if you have one and see if you get a reading (continuity) across the terminals on the valve.
I'm thinking icemakers have micro switches inside them also that sends the power to the inlet valve. I may be wrong on that. Its been a long time since I did any work like that. Actually did little with icemakers, mostly ref's, washers and dryers. But, I do know that solonoids such as the inlet valve can receive power and not work if the coil has no continuity. In other words the circuit is broken inside the solonoid.
