That's not correct. You have 2 different sets of coils .a pick coils that picks the valve plunger up & a holding coils to hold the plunger up. A weak holding coil will loose it's grip on the plunger & the dryer burner will cycle off

dryer


sounds like an airflow problem, did you take apart all of the venting and clean or check it? does it have any flex tubing attached, is it getting kinked. do you have the dryer pulled out of place? 99% of time that I see the problem you describe it is an airflow problem. unhook it from the vent all together and run it for a bit. if it cycles off after a few seconds then most likely you have a bad thermostat.

Kenmac,when coils are weak- if you have flame for one or mutiple cycles, depending on how weak one of the coils are- usually the secondary coil- after the detector cycles off , the weak coil is now electricaly open. so the next go around[detector cools down] the igniter will cycle on and off via the detector but no flame.

I have had these dryers short cycle & sometimes not fire at all because of bad holding coils. You could ohm the coils to find the bad coil. Also, when they are going bad, The dryer flame will be on you hear the plunger chattering because the coil is weak all of a sudden the coil can no longer hold the plunger drops & gas goes off. The dryer flame may restart or, it may not restart on next cycle
