Product review (1 stars): Poor quality after-market part; Poor service from "partshouse"
The original dryer element lasted 5yrs; this Napco after-market part lasted only 1yr -- and with low usage.  I asked "partshouse" to replace.  The exact exchange follows:

Me:  "I purchased and installed this part a year ago.  It worked fine for that year, but has already burned out.  It must have been defective, because the original part lasted from 3/07 until 1/12.  The dryer receives low-to-average use for just a family of two."

Partshouse:  "This part has a 90 day warranty. You will have to order another one."
