Thanks for quick response. I'll check power supply at wall. Two questions:
Is it worth cycling through these control units and replacing every 3-6 years vs switching brands.
I am semi-handy (have replaced dishwasher pump impeller before) - is the board replacement something that a punter could do?
I don't if we are still good for more questions. I opened the unit, so the largest (main control board) had two burnt areas. Ordered a replacement and installed, powered up and no response. what's the next piece in the energy chain?
You had predicted that the larger of the two boards would be burnt and suggested a likely part number which matched the toasted part. I replaced this piece shown in page below from Sears parts...
Completely dead - I verified power and have de-installed it and am contemplating next move. The one item that I may have fouled up on was the 6 or 8 pin plug that connects to the glass-top and controllers to the main board. I didn't make note of which of the 3 options that it could be plugged into were correct. One option had what looked like minor abrasions in the conductive part (ie plug and unplug), so I started there as the others were clean. There is still one more option there, but before I dig into it again and undo all the screws I am going to research the likely correct jack.
