Question about Goodman GDS80904BNA Open Flame Heater
These furnaces have notoriously bad circuit boards. The light will give you a diagnostic code and after you have replaced every component there it still will not work right. Need to know more specifically the order of events happening. the blower should turn on (draft blower) then after a second a click and you will see the ignitor glow bright orange then click the gas valve opens and the burners light. most of the time this will all happen and then the flame in all burners will go out and it will attempt the whole process over. if this is the case turn power off and then remove the circuit board from the 4 retainer clips and look at the back 9 times out of 10 the board will be dark brown in one or two spots large spots at that. time to replace the circuit board. They have updated the board and it is being made by a different company now. Take a picture of the board before you remove any wires so you can replace the wires in the proper location.

You may have a plugged air filter, the air intake or exhaust pipes could have a blockage causing the switch from closing. The little tube going from the inducer blower to the pressure switch could have some moisture or drbris in it. The condensate hose from the inducer to drain could be plugged or you could have a bad inducer or pressure switch.
