Hope that works for you.
90% of ice machine problems are water or air related.
If the problem reoccurs check the harvest relay in the control box for corrosion or faulty contacts.
You stuck with it and found a problem.
Too many techs want to go in for a quick fix and start making adjustments or change parts unnecessarily.
I always start my I/M diagnostics by making sure the adjustments are set to factory specs if it is a machine I am not familiar with.
Secondly, I check air flow,leaky water valve and evaporator plate for buildup.
Always do a ice production checklist regardless of the brand of machine. Lots of external problems will mimic internal parts.
Some times the biggest problem has the easiest fix.
