Product review (5 stars): Whirpool Duet Dryer drive motor
My original motor was manufactured in Mexico and lasted just over 10 years of heavy usage.

I researched this part extensively and "IF" it is actually an OEM replacement ( [...] ) the price from the Whirlpool site on 12/18/13 is $156.18.
I ordered it with Amazon Prime so if there are any issues, I will be able to exchange or return it with no drama.

FYI for anyone considering this repair here is a YouTube link to the process (please note that there may be sight differences due to the model/manufacturing date:

Updates after I receive and install this motor.

**12/23/2013
The motor came this morning after a slight delay with the Christmas insanity that UPS is experiencing.
This is an exact OEM replacement motor for my Whirlpool drier, it even says Genuine Whirlpool Replacement Part on the box and was the exact same Made in Mexico motor that was originally installed.

Why save a few bucks with other motors offered and then end up having to make modifications?
This was a direct replacement, and the drier is now working perfectly.
This motor came with instructions and new electrical connectors for some older model motors it replaces to bring it up to current safety spec.

I did not opt to change the drier belt, pulley or support rollers as the all appeared to be in excellent condition, but if they had needed replacement this would have been the time.

All told this took me about 1.5 hours to replace and much of that was cleaning the dust out of the inside of the motor compartment.

Just watch the video link that I posted 1st and you should not have any issues.
