Product review (4 stars): Whirlpool W10174746 Electronic Control for Dryer
The first one I got lasted about almost four weeks and died.  Amazon, as always, replaced it without any question and the replacement has worked great for almost four full months now and I expect no problems with it.  The board cost me about $115.00 and I was able to install it in about fifteen minutes saving me a service charge of at least $75.00 plus the service company wanted to charge me $300.00 for the exact same board.  This made a total savings of $260.00.  Thanks Amazon.
