Product review (4 stars): Excellent part for a quick and easy repair if handy
If you are handy, this fix should NOT scare you.  The part is basically a simple heater coil that slides in.  Do yourself a favor, If you have a Kenmore (Whirlpool) dryer, look up how to repair using this part.  You will be amazed at how easy it is and you can save yourself quite a bit of money by avoiding a service call by a technician.  Good luck!!!  and be careful.
