been to this friends machine the ice will not stop making even if the metal level switch is up. there seems to be a module behind the square cover. not having worked on these before i thought i would pick your brains first.
If the bar is up and it is still making ice then it is the module at the front you will need. It is probably the white plastic cam that the metal arm is attached to but this is only available as a complete module.
