I went on the forum with the model number and did a search. Based on what was previously posted, I replied to the same thread for my model number. It was likely to be one of two parts, but I wanted to be sure in the troubledhooting, so I asked an additional question, which was promptly answered. I ordered the needed part and followed the directions previously posted. Problem solved, except for the fact that the control board needed should not have failed in the first place. But that's what happens when quarterly shareholder stock profits outweigh all else.
