I too have this problem and wish to know which of the two coils you think should be replaced, if only one... the "main - 2 terminal" or the "pilot position - 3 terminal" coil? Thank you in advance for your reply.

This gas dryer uses automatic ignition. Their is no pilot. The gas valve assembly consists of a glowbar/ignitor, a flame detection sensor and a pair of coils all cleverly wired in a complex series circuit. When the fuse allows the control to flow power to the gas assembly all of the gas assembly components are energized. The coils cannot open the valve however as long as the ignitor is glowing. When it gets red hot it heats the bimetal inside the flame detector which shuts off the power to the ignitor. When the ignitor glows it holds open one of the gas coils. The other gas coil has enough juice for it to open, then ignition occurs. Depending on how many clothes is in the drum and how wet they are detirmins a burn period. With nothing in the drum it heats up to temp promptly and therefore the gas stays on a shorter period of time. So what can go wrong? The fuse mounted next to the control on the blower housing will melt if the blower wheel is wobbly and worn out or their is a lint build up causing air flow blockage. The control stat might be bad (doubtful) unless it ain't shutting down and is melting the fuse. If power is indeed getting to the gas assembly I would check the sensor first. if it is open circuit no power will get to the ignitor. If that is fine check the ignitor for continuity. Note: If it works a little but quits, replace them solenoid coils on the assembly. When they get aged they tend to quit when hot. My home movie of how it works:
ONE DO A COMPRESSION TEST ANYTHING OVER 120LB ITS OK TWO DO A FUEL INJECTION SERVICE CAN ONLY BE DONE AT A SHOP COULD BE DIRTY INJECTORS OR BAD 1 OR 2 INJECTORS TRY TO GET CODES LET ME KNOW WISH CODES GO TO AUTO ZONE THEY WILL DO FOR FREE GET CODES OK LET ME KNOW ILL HELP YOU DO NOT AD ANYTHING TO YOUR GAS TANK NO FUEL CLEANERS FOR ANY RESON OK
Yep. If the ignitor is working properly and the dryer won't light, then it is most likely faulty gas valve coils. These electrical coils are right above the gas valves. These solenoids, when energized, open the gas valves and permit the burner to light. If any are suspected of being faulty, it is recommended that both (all) be replaced at the same time. Hope this helped and best wishes.
This is most likely faulty gas valve coils. These electrical coils are located just above the gas valves and when energized, these solenoids open the gas valves and permit the burner to light. If faulty, the gas valves cannot open and the burner cannot light. Due to the difficulty in testing these solenoids, it is recommended that both (all) be replaced at once if any are suspected of being faulty. Hope this helped and best wishes.
The gas valve coil solenoids are most likely defective. The coils should be right above the gas valves. They are hard to test, so both coils should be replaced at the same time. When working properly the coils open the gas valves when the solenoids are energized. Hope this helped and best wishes.
I would take a look at the gas coil solenoids. The gas coils are right above the gas valves. They are black electrical coils. When energized, the coils open the gas valves. If one or more of the coils is defective (bad solenoids), then the gas valves won't open and the gas cannot ignite. Because it's difficult to test the coils, it is best to replace both (all) of them at the same time. Sure hope this helped and best wishes.
Hi, It sounds like that the coils on top of the gas valve are not opening the valve later in the cycle. They get weak enough ovwer heat and will not open the valve. You can listen for the ignitor to click on and then you can hear the gas ignite. If late in the cycle you hear the igniter click and then no gas ignition, change the coils.
You should also make sure the vent going to the outside is clear of any lint or kinked.
I hope this helps you. Please let me know if I can assist you further.
