Here is a clip of this occuring. Still not working. It is cold cold.. I've tried unplugging the blue wire on gas valve and then tried. It does try to light after that. . Does that gas valve have a feedback stating it's open?? Also the thermostat is unplugged and jumpered out...

Hey, did you find anything out yet? I have a UDAP45 with very similar issues. Other than mine will only run the venter motor, then as soon as the ignition starts or tries, everything shuts down and then restarts. No codes, not locked out. Any suggestions>? Thanks.
