If you move the lever that senses the levelof the ice, can you hear
any clicking or sounds that sound like a valve opening and closing.
If dead silence, either the switch or the valve is most likely gone

Yes, I hear clicking. This happened while the water was disconnected
but the unit was still running, and the button to make ice was still
on for a couple of days.
