My experience was that at room temperature, terminal checks were good but after running the dryer for 15 minutes or so, the resistance on terminals 1-2 (on the three terminal coil) went to infinite. Also, initially the burner lit but after the 2nd or third cycle, it no longer lit.

I found the step by step explanation of the operating sequence very helpful and concise. I did not quite follow the second last sentence in the 'Call for heat' section. The sentence says, "If the flame goes out the sensor will cool and the contacts will open bypassing the secondary coil .....". Shouldn't it say that the contacts will close? Overall an outstanding outline and thank you so much for the information.

My name is Tom and I had the EXACT same problem. Your explanation of how the gas valve works is splendid. I wish I had found this page before I called the repair service and paid an $80.00 service fee. AND the service man was not able to pinpoint the problem. He said instead of buying a new gas valve, buy a new dryer!! I tested the resistance of the coils and found one coil had a reading of 1900 ohms. The coils were replaced and the problem went away. I didn't have to buy he whole valve.
Thanks for the clear explanation of how a gas valve works in a dryer.
