Ice maker stopped working. Pulled unit - connections all looked good and when tested there was 110v between the black and green wires on the wiring harness - the remaining two wires had no significant voltage), but eject motor appeared to be stopped in the middle of a cycle. Switched leads on fill valve and water filled tray when door water lever was pushed, indicating the valve to the ice maker will work when power is applied. Based on evidence it looks to me like it is a bad motor (part
AP4359694), however, not knowing how the motor is controled, I can't rule out an upstream part that controls the motor. Suggestions?
