I have a janitrol furnace model GDS80453ANA. When the thermostat directs it to turn on, the draft inducer turns on, a few seconds later the igniter glows red, the gas flows and ignites in only one of the two burners. After a few seconds the gas turns off....as it should since the flame detector is in front of the burner that does not ignite. After a few seconds the process starts again but this time both burners ignite. This happens every time it is supposed to turn on. I had the burners replaced. No faults on the control board.
