Hi, No heat originally. Checked vent for clogging. Bought, thermostats, thermistor, radiant sensor, door latch, igniter, coils, new motor(centrifigual switch bad, motherboard, console(repairman suggestion). Tested every wire for continuity from motherboard to each component. Tested each hot wire to ground. All components working. Each console settings work.
The dryer starts, centrifigul switch clicks, then coils, igniter glows, gas starts then shuts off 5 seconds, repeats this and then whole unit shuts down prior to end of cycle. Every bit of advice is needed.

Is the dryer completely assembled or do you have it apart with the drum out?

I've got the drum out.
OK, that's the problem. The blower pulls the air from the open end of the gas valve duct cone. That pulls the flame down the duct cone to the drum. Without airflow the flame piles up on the thermostats and shuts it off. Reassemble the dryer and problem solved.
