Product review (5 stars): Dryer not drying? Try this first!!!
Worked like a charm for my maytag dryer! Our front load dryer just stopped drying one day. After researching DIY fixes I found it was most likely the valve coil and that most manufacturers use this whirlpool one in most of their models. Of course,  Do your own research for your model of dryer but this was WELL worth the time spent looking into because my dryer is now drying once again and has had no problems since we replaced this part a few months ago.
