Product review (5 stars): Works as advertised!
My Whirlpool washer a few weeks broke on me and my wife.  it's only been in service for two years.  Basically the washer would just stop altogether in mid-cycle.  Sometimes pressing pause and start would move it along, but sometimes it doesn't.

After doing some research online I was able to find the tech sheet of my washer online.  After running through the tests I found my error code to be F7 E0, which most of the online supports indicate to have this Actuator replaced.  I thought to give it a try, as this thing is less than $40 on Amazon.  The worst thing that could happen is that it doesn't work and I would call Sears.

I actually watched through Trace's videos fromt the review above and it was very helpful.  I made sure to remove the water pipes carefully, and I used a cardboard box to land the washer on its front.  Using standard tools that I have around the house I was able to get this Actuator replace in less than 15 mins.

Putting everything back, calibrate, and did a test run again.  The error code goes away and it's working as it normally does.  The wife is happy!
