Amana icemaker

No ice! I hear "groaning" like the maker is trying to do something, but no ice. I’ve checked the water inlet valve (but did not jumper it with 120 V)(which I need to do next), but got a voltage from the icemaker to the valve of 0.2 volts. Yup, that’s POINT TWO volts. Would that seem to indicate a problem with the icemaker itself? Or is that a normal state when the icemaker is NOT calling for water? ??? How do I t-shoot the icemaker itself?
