Product review (3 stars): This part may work, but it might not solve your machine's problem.
This little part can totally save you from having to scrap your 12-year-old machine. I highly recommend searching out the YouTube videos available on how to install this part. I think this was the sensor that went bad on the machine (stuff is not made to last these days), but we had a bigger problem with the board behind all of the buttons and settings on the machine. That part does not exist anywhere except in working machines. They're not manufactured any more, and are probably the number one reason these machines don't last.
We knew it was over when the sensor worked, but the problems continued (using the diagnostics found in the handy youtube videos). The washer went to the curb for scrap, and I got an out-of-box simple top-loader for less than $300 in July (best time to get new appliances!!!).
