Does anyone know if there's been a wiring change internal to the Whirlpool cloths washer timers, or in the harness that connects to them?

I bought a new timer for my washer and the motor just humms until its thermal breaker trips. If I replace the old timer, the motor works fine. New timer, humms and doesn't work. Old timer, works fine... etc.

Washer model number is KAWE777BWH1. Timer part number is 3946476. I've confirmed this is the correct part number, and it is also the same number as on the labels of both the old and new timers.

So.. is there a wiring harness change or something that I also need to do in order to use the new timer?

That's what I thought too, just thought I'd ask. I'm not in the industry -- maybe whirlpool issued some wiring update for my 16 year old washer that makes it compatible with the new timer. Good to hear that's not the case since I'll still need to replace the timer.

And the place refuses to take the part back (long irrelevant story).. lesson learned, and a google review posted in the hopes of helping others avoid making the same mistake with that supplier (not this site, BTW).

Thanks. That's pretty much what I gathered, which is why I'm here. And I intend to order the other parts I need from here too.. I like to help support places that have good forum scenes going on with my $.
