Product review (1 stars): Amana/Whirlpool Clothes Dryer NED7200TW
We had this dryer installed in 2009, and have had the heater element replaced three times, that's once for each year of use!  We made sure our lint trap was cleared after each use, and regularly check and clear out the vent pipe of all heavy lint deposits so, we are certain these factors did not contribute to the heater element failures.  If anything, vibration and poor element design are the issue here.

WE DO NOT RECOMMEND THIS PRODUCT; however, if you should purchase it, make sure it is under a service contract.

The old Bendix clothes dryer I grew up with NEVER had a heater element failure in all its years of use.  Just another testimony to the fact that, "...They don't make 'em like they use to".
