Product review (5 stars): No heat gas dryer
Reasonable price and prompt delivery with Amazon prime.  This coil kit should solve the problem if after starting on high heat the igniter glows, soon fades off, and the burner does not ignite.  If the igniter continues to glow for several minutes, it is likely a different problem and the coils are not to blame.  You can check each coil by removing them and measuring the resistance (ohms) of the coils.  In my case the coil with 2 conductors measured open meaning it was burned out.  The coil with 3 conductors should show approximately 500 ohm, 1500 ohm, and 2000 ohm depending upon which 2 conductors are measured.  These coils are used on many different makes and models of gas dryers but not all.  Need to determine the correct part.
