My Maytag gas dryer is not drying. I took off the front panel and cleaned of all the internal dust off thermostat, the flame sensor and exhaust lines. When i start it up the drum and impeller spins, the igniter glows and the gas valve opens and the flame stays on (I have the lights off so I don't influence the sensor.) and everything seems to run okay. When I close it up I see the igniter glows then the gas valve clicks then it seems to stop heating.??????

Do I have a bad flame sensor or a bad thermostat, or something else?
