Product review (5 stars): Appears to be OEM (printed on packaging and stamped on product)
I was nervous about buying this replacement part because others had mentioned they received items that were not OEM (meaning not an official Whirlpool part).

I'm happy to report that the box I received was (at least due to the printing on the box) an official Whirlpool part. But what's more than that, the patent numbers were stamped on the actual metal part, just like the burnt-out part that needed replacing.

So, depending on which seller is selling the item, you may get someone trying to sell a knock off, but at least the part I got from Parts-4-Less seems to be OEM and it works great.

Note: Just remember that this part is the heating element only. You need to save the temperature gauge from the old unit and apply it to this one, or order a new temperature gauge. If you're not familiar with that that part is, it's pretty obvious when you see the new part that there is an opening where something is supposed to go. There are some great instructional videos online that show you how to remove the old part and put everything back together.

Just note, that some videos showing how to replace the part may be for different dryers. For our dryer, all that was required was to take off the main back plating off the dryer, and the small black plate that covers the power cords. Your's may be different, just check online for a video showing your model and this repair being made.

It's also probably not a bad idea to clean out any lint build up in the dryer and connections.
