Hello, I'm having trouble with my ice maker; it works intermittently at best. I've removed it multiple times, taken it apart & let it thaw & dry out overnight. Worked at first then stopped ejecting ice. I tested point N & L and got around 34 volts. I shorted T & H and the ejector part rotated & ejected the ice that had been stuck in there, and the water filled up again. It seems to stop ejecting whenever the bin fills up & the ice has to sit in there for awhile. The optics seem to be working fine. What else can I do?
