I have a problem with no heat on this Frigidaire FLSGC72GCS3
gas dryer (stacked unit on top of washing machine) On observation when it's cold the ignitor glows gass kicks on and it runs fine-heats up, gas shuts off then the next time gas is needed to cycle, the ignitor glows but no gas and it continues this way till it completely cools down.
My question is do gas valves act intermittently when its warm or should I be looking elsewhere???
If the thermostat was bad or the high limit will the ignitor still glow at intervals??
