Dryer was not drying clothes. Checked and had good continuity on both thermal sensors. Changed out gas solenoids. Dryer fires up and runs for about 5 - 7 min and then I'm guessing the cyclng switch shuts the gas off. After a few minutes the ignitor starts, gas ignites and runs for about 30 to 45 seconds and the flame sputters and goes out. I think there is a faint smell of natural gas. Is this a faulty cycling switch?
