Serial # 14048031AV. Purchased 2/2003. The unit had a list of operational problems, I replaced the Control Board which had burned-out some of the electronics. After replacing the Control Board, we ran the unit successfully through 1 or 2 cycles. This morning, the unit is back on the fritz, so I opened-up the door and found that it has destroyed the new Control Board. On the Control Board, R53, R56, R57, R58, R59, R60, R61, R62, and R63 have overheated and burned. These are the same resistors that were destroyed on the old Control Board. In particular, R57, R58, R61 and R62 show evidence of the most heat damage and I was able to easily scrape their remains off of the printed circuit board with my fingernail. I do not have a wiring diagram. If you know what load these resistors supply, maybe I can troubleshoot further to determine what part/parts are demanding high current and ruining the control board.
