Hi Jefinch,

I had the same exact situation with my Maytag SG1000.

I tried installing the least expensive part first, the touch pad, and Voila! Instant functionality! One touch does it!

So, for future reference, if it takes a prolonged pushing of the touchpad buttons to get it to work, it more than likely is the touchpad, not the more expensive circuit board.

Also, inspection of the ribbon cable from the old touchpad showed that one or two of the flat ‘wires’ appeared to have leached / bled out. Perhaps that’s what caused a gradual build-up of resistance leading to the eventual failure.

I'm posting this in hope it can help other folks.

Lastly, that humming you mentioned is the transformer. It hums softly whenever the machine is plugged in. That's normal.
