Product review (5 stars): Works great in my old Maytag Neptune
Product arrived 1 day early and in excellent condition (box in a box, with lots of padding).  The instructions were easy to understand and it took less than 2 hours to remove the old motor and circuit board and to install the new ones.  I was a little worried that there would be fit or compatibility issues, but it all fit perfectly.  Our 19 year old Maytag Neptune washer (MAH4000AWW) is back up and running like new.  Bonus, I saved well over $300 by doing the job myself.  It didn't take any special tools, and should be something an average home owner (like me) can do themselves.
