Product review (3 stars): This is a generic part
The product I received was not a genuine whirlpool part and did not come in a sealed whirlpool packaging. I am not saying it does not work but it is not as described.
Update July 2017:  This part cut off (white part) after 5 months.  Replaced with exact same part and it failed after about 1 month.  My ducts are clear so not sure the cause.  I cannot say if this is a poorly made part or a good part.  All I can say is it has cut off in a short period of time...ie...opened so the heating element does not work.  I reordered a new FSP (OEM) part from Amazon.  We'll see how that goes.
