Have 3 Whynter chc-251s coolerators, 2 are not cooling now. Started as display temperature was lower then set temperature so it would not cool till I set them at 54. Now they stopped cooling but fans keep running. They are no longer under warranty and called Whynter, their reply was send them in. I live in Florida so they would need to be shipped to California, quite expensive and Whynter would not say how much repair would be, I asked could I replace the board or other parts, they said no parts available now and would not say if I could if avaiable. Main board, heat sink, temp board. I wonder if a local repair company could repair. It seems the part that reads the interior temp went bad first then got worse. Any ideas.
