Recent Review: 6/4/13 He determined that the computer boards were bad on both appliances. The Amana refrigerator has 2 computer boards, a high voltage and a low voltage; one is still available, but the other is no longer being manufactured, and that one regulates the defrost cycle. 6/11/13 Because we were trying to find options for not having to replace the refrigerator ($$$$), we called Sebastian back to check thoroughly the refrigerator to make sure components besides the computer board were OK. They were. So, we ultimately decided that, for now, we would manually defrost the refrigerator whenever the alarm goes off (every 1-2 weeks) since the refrigerator works well otherwise. 6/4/13 The Kitchen Aid oven computer board is still being manufactured, but was back-ordered. 7/9/13 Sebastian came with the new computer board, installed it, and---nothing. In checking it carefully, we discovered that it was defective--3 contact points were not soldered properly. He returned it. (The computer board price was $396 + tax). 7/18/13 Sebastian came with the computer board, installed it, and it worked! Sebastian was extremely prompt in coming and answering our calls. He is professional, patient and helpful.
