The start/Cancel button works all the time, so we can use the machine, but the other buttons do not work. Sometimes we can change the cycle, but if we're not lucky it gets stuck on one that we don't want. (It's stuck on heavy load, now).

I hate the idea of wasting money on a $100 part that doesn't fix the problem, so I am looking for advice. I'm pretty handy, so if there is something to check, I can do that.

Thanks !!
