Question about Goodman GDS80904BNA Open Flame Heater
If after replacing the pressure switch its showing the same problem then try this --------- pull the exhaust fan end of the hose that runs from the pressure switch to the exhaust fan. Then snipoff about 1/4 - 1/2 inch off the hose, and attach the hose back onto the exhaust fan and check out. ------------- if still the same problem then is the faulty board which needs replacement. ----------- you can get new board from www.repairclinic.com or from www.partsselect.com ----------------- this will help.please do rate the solution.thank you for using fixya.thanks.keep updated.

If your igniter comes on but no ignition, that eliminates the possibility of a bad or clogged pressure switch, high limit or flame rollout switch.
This issue may be due to one of the following reason
1)control board must be gone bad,
2)gas valve going bad.
3)some loose, corroded, or faulty wiring.
Before the igniter comes on the furnace does a self diagnostics to ensure everything is working, or the furnace will not make it to the igniter sequence.
Induction motor, pressure switch/s, limit controls are closed…then comes on the ignitier, gas valve opens, pilot runners and burners ignite, flame sensor detects the flame, blower comes on and all operations are working.
Checking all the three possibilites would solve your issue..
Please leave me comments, if you need furthur assistance
