The Control Pad started loosing fuctions, one at a time until finally my stack unit would not even come on.

First I removed the control panel and board (which requires moving a total of 6 screws. I cleaned the board and touch padthem of the dust that had accumulated over the years and put them back to make sure that they needed to be replaced and when that didn't seem to help, I knew my options. The parts were $350.00 and although that might seem like alot.
I had watched a repairman do this 10 years earlier and saw how simple it was. To have the repairman do it, cost me over $600.00 last time.
He recommended that I replace the unit back then. This is one of the easiest repairs I've ever done. I 'd do it again, if I had to. At this rate maybe I'll get another 10 years out of my washer / dryer stack unit.
