Product review (5 stars): This is the one to get!
My local appliance part store wanted $130 for this part.  I found it on Amazon for $50.  Of course I was skeptical, but ordered it anyways.  It arrived in an authentic whirlpool box, so I was happy about that.  It's identical to the old one, so it's an exact match.  I installed it today, and turned it on, and guess what?  It works!  It works great!  It's also very quiet.  Other reviews say that it's loud, but maybe that was poor installation??  Mine is very quiet.  I'm very happy about this purchase.  Thanks Amazon!
