Product review (1 stars): Cheap quality and warranty not honored unless 'professionally' installed.
2 things:  they don't make these like they used to.  This one has lasted 4 months and is starting to hum and smell of electrical overheating.  Also, if you install it yourself - which anyone with a screwdiver can do - you void the warranty per the manufacturer.  Apparently Amazon doesn't honor the warranties directly any longer.  Buy an aftermarket motor, not a whirlpool, as the quality you get will most likely be the same with both - lacking.
