hi everyone:
i have to repair a scotsman cme1356 ice machine, the problem seems to be that the bin full light wont turn off and dont start because it understand that there is ice but no. i replace controller box, eye sensor, temp sensor and nothing seems to change.

There's no use in throwing parts at it.
