Product review (5 stars): Door Locks But Spin Cycle Isn't Working?
If the door's a lockin' but the washer isn't a rockin' then this could be exactly what your washer needs. If I hadn't read about it on the Internet then I probably would have missed this simple and inexpensive fix.  All it took was a pair of needle noise pliers, a Phillips screwdriver, and 5-minutes of my time.

Of course there could be other reasons why your washer isn't running the spin cycle so be sure and do some research before spending money on parts.

I ordered on a Thursday and received the part the following Monday so a big Kudos to the seller for fast shipping, and additional kudos for the minimalist packaging. They've been added to my bookmarks should I need more appliance parts in the future.
