Product review (1 stars): Spend a little bit more money and buy the Whirlpool Factory original part.
Like others have said, this motor was noisy from the moment I installed it. The motor sounds like it surges, gets really loud and then drops out and quiet again. The factory original part never did this in the 16 yrs it worked, in fact you could never even hear it working unless you opened the freezer door and listened closely. But the sound isn't the only issue, because of its surging behavior the fan isn't keeping the refrigerator as cold as it should. Buying this ERP motor was a complete waste of $18, save your time and just spend a little more for the Actual Whirlpool replacement part.
