I have had bad coils on the gas valve act like this .. once the coil heat up they do not hold the valves open.. to check clamp on 2 voltmeter too each coil.. if you still have voltage to both coils after the flame goes out.. you have bad coils on your valve..

Hello again.  Here is my status.  I installed new gas valve and coils, installed new thermistor and the flame still goes out after 10 seconds of turning on.  I then checked the moisture sensor and it is ok.  I have so far checked or replaced everything except the computer board.  This may help as a clue.  The only way I got the flame to stay on was to detach the Hi-limit thermostat from the flame housing or duct and leave it hanging off to the side.  I have a new thermostat installed.  Is there a software temp setting that could be set too low for this to trip or is the flame too hot and tripping this thermostat?  Is this a PCB problem or circuit board board?  What else can this problem be?

More information:  In Normal mode, after one failure the ignitor will start up again and after the flame goes out for a second time the timer sets to 1 minute and the "Drying" and "Cooling" indicator lights to come on at the same time.  After 1 minute All indicator lights come on (Drying, Cooling, Wrinkle, Prevent) and digital number display indicates blinking light alternating around a track. Dryer continues to run.

Should my next option to replace the PCB board?

Try running it without the vent connected.  You may have a restricted vent.

Vent was cleaned out to the top of the roof.  That was the first step for a resolution

OK I have exhausted all attempts to resolve this problem.  I have replaced everything and checked everything.  I do know that the flame trips the Hi-limit thermostat and flames out then resets and tried again.  It is too hot in the duct assembly.  No air blockage and I have already changed valves and coils.

Have you run it WITHOUT the vent connected just for testing?
