Product review (5 stars): Whirlpool W10006355 Actuator  - For Whirlpool WTW4800XQ1
Exact replacement part I needed for my machine(Whirlpool WTW4800XQ1).  Washing machine wouldn't spin the clothes dry, but sounded like it was trying to click into that cycle so I bought this to replace the old actuator.  If that didn't fix it I was going to replace the lid switch, but that did it.  Great price.  Watched several videos on the internet on how to swap it out and it was a piece of cake.  Make sure you mark the old one with a sharpie so you don't accidentally reinstall it.  I almost made that mistake when I had the old and new ones in my hands when I was comparing them.
