Question about Goodman GDS80904BNA Open Flame Heater
If your roll out is open it is due to it over heating. Your burners when they are lit are rolling back and opened your roll out. You need to check your exhaust venting to see if is clear(no restrictions). Also, your heat exchanger could be cracked enough that when your indoor fan comes on it puts enough positive pressure on your exhaust that it won't exhaust correctly. One way to check for a cracked heat exchanger is to watch the burner flames when they are lit and see if they move(flutter) or come back toward you when the blower fan starts to operate.I hope I was able to help you!!

Hi, I just wanted you to know if you are still having a flame roll out condition, yes the other tech was right by checking for a cracked heat exchanger, or obstruction in the flue. I have seen and found birds nests in the flue on the roof. Also, rusted up burners, plugged burners will cause this. If you have a roll out error, this tells me this furnace is a newer model? The switch will be located at either side near the burners and can be reset after this condition is found. If all appears good, I have seen a gust of wind come through and open the contacts on this roll-out switch. Just food for thought.
