Product review (5 stars): It worked!
We used the tool where it says if this will work in your machine or not.  I was a little hesitant when it got here, because the revision number was different...but it looked right, all the specs were right, and there's no way we'd be able to get someone to come to the house to LOOK at the washer for less than a hundred dollars, much less fix it.

Worked perfectly.  Once we remembered to turn the water back on. ^.^

Problem was the same that most people looking at this part probably had-- suddenly the washer wasn't getting clothes very dry.  They'd be dripping wet, no matter what the setting.  And half the time it wouldn't work at all.

Looked online, found out it was either this or the magnetic lock, the lock was obviously working.  Opened up the bottom to see if there was...oh, a flashing sign that said "hey, it's not spinning because of this!
No luck. ;)

Ordered the part, attacked the washer with a screwdriver.

Two screws to get the guard off, two screws to get the old part off, a push-to-unlock wiring setup, and don't freak out when you have trouble putting the new one in you just have to line the plastic thing in the back up with the hole; taking it out it's much smoother. You do not have to force it, just wiggle it around a little and remember to stay calm.  (Really not easy, I know!  We have five kids and it's spring, I had a MOUNTAIN of clothing to get done!)

Put the guard back on, got the machine back up and hooked up, told it to rinse as a test, freaked out because we couldn't hear any water going in, turned on the water, it worked, yay!
