Product review (1 stars): Vendor good, Parts bad...
First set had a bad primary solenoid, vendor was very good about replacing them without return, the replacement set had a bad secondary solenoid.  Mixed and matched to get the dryer working, after the I got everything working, the replacement secondary only worked for two days, then went bad.  Vendor was good about returning the money, but I suspect they order sub-standard replacement parts.  I ordered OEM parts from an appliance part shop and have not had a problem since.  Mary C is happy, I am happy :)
