I have a 15 inch wide whirlpool under counter ice machine. Its a 2006 model and has made great ice for over 15 years. Model # GI15NFRTSO. I dissembled it and replaced the control board. re assembled it and it turned it on and it started making ice again. happy me patting myself on the back. during the second harvest it shut off , exact same as before. The only other thing I can think of is the power transformer. I cant keep my fingers on it very long. I've spent $300 on the control board and the transformer is around $200. I just don't see anything else that could cause a complete shut down like this. Anyone agree or see a different cause? new one are $2500 so im willing to spend the money but only on the parts that I really need.
