My Goodman Gas Furnace diagnostic light indicates a faulty air pressure switch or restricted air supply vent. Vent appears clear, vent motor assembly works. I replaced the air pressure switch but the diagnostic light still indicates the same problem. Is there a reset switch or means of resetting to clear the computer or integtrated circuit board to clear the default reading?

Try clearing the port where the pressure tube connects to the draft assembly , sometimes a little rust or debris gets in there.


Also the tube may have water in it so clear that too

Power off for 10 seconds to remove fault code.. it will not reapear unless the fault occures again
