Product review (5 stars): looks factory OEM.
My HE2 dryer is a POS.  I hate it.  This is the second time we replaced the heater element.  First time I paid 200$ for a tech to fix it, and the second time I did it myself.  This is an excellent part... came marked in a whirpool box, so it appears to be a factory replacement.  installation of the new part was a real bear of a job.  If you DIY, make sure to mark the connecting wires so that you can put it back properly.

Put everything back together, said a quick prayer, and plugged in the unit.  Houston, we have heat again!  Youtube has a couple of DIY instruction videos which were very helpful.  Good Luck.
