Goodman gas furnace flame roll out
I am having flame roll out on my goodman gmh95 gas furnace ,checked venting ,,no troubles ,inducer blower seems okay ,,no accumulation to worry through tubes or heat exchanger . Wondering if defective gas valve could cause this ..Flame will actually have roll out before supply blower activates Had control module dip switch on Single stage tried 2nd stage and seems like it will not sustain flame long enough for supply blower to activate now Any suggestions or typical problems ?? Also this problem of rollout is located on the 1st burner tube of 3 other 2 burner tubes show no sign of trouble

Welcome to the forums.
Although not very common..... it could be caused if the pressure regulator in the valve had a problem. That would be something you'd need to have a technician or your gas company check.
It sounds more like a flue issue...... you're sure the PVC pipes are clear and wide open ?

Pipes are clear and also can hear disruptive air pattern on prepurge cycle Am getting inspection camera to check interior of burner tubes and heat exchanger areas .As I mentioned previously the roll out occurs even before supply blower activates

If this is a condensing furnace, check to be sure the drains are clear. I had one like this earlier this winter and could not get it figured out as the clog in the drain would slowly let the water drain out by time I got there. It took at least 4 cycles of the furnace to fill the lower heat exchanger area full of water to prevent the flue gasses from draining.
Check all of the drainage tubes to make sure the water is draining out of the heat exchanger.

If you are the original owner..... Goodman has a ten year warranty on most of its heat exchangers.
Labor to replace is not included in that warranty.
