Product review (5 stars): Dryer would heat initially, but not again.
Fixed our Kenmore front loading gas dryer.  The dryer would heat when you first turned it on, but then would not heat again.  You would see the lighting coil turn red, and hear a slight buzz from the gas valve coils, but the gas would not turn on.  Test your coils with an Ohm meter.  On the 3 connection coil the reading between pins 1&2 should be about 1.4K Ohms, pins 1&3 should be 0.6K Ohms, and pins 2&3 should be 2K Ohms.  On the 2 pin coil the reading should be 1.3K Ohms.  My 3 pin coil was bad.  Between pins 1&2, and 2&3 I would get either an "open", or something like 250K Ohms.  The Ohm meter would greatly fluctuate when taking this reading.  Also with the new coil, the buzzing went away.

Amazon prime is great.  Ordered on Friday, and the U.S. Mail delivered the part on Sunday.
