There is no reset button. The fault will clear itself upon cycling power to the furnace once the problem is corrected. The furnace has to establish air flow before it starts the ignition cycle. Check and make sure that your inducer motor is running during a call for heat and that the flue is free from restriction. eg. bird nests, animals, snow, ice etc.

where vent motor is there is usually a hose coming off which oressurizes when vent motor comes on, take hose loose **** or blow in it, take tooth pick and stick in all ports where hose connects (could be clogged) when sucking on hose you shoul hear pressure switch click each time you pull a vacumme, if fan has switch on back of fan as some Goodmans have the vent motor may need to be replaced.

make sure the hose from vent motor to pressure switch is not plugged, put tooth pick in both end normally the fan port is plugged.

SOURCE: Furnace not kicking on
Kill power to furnace and retry heat. Sometimes high winds will cause a back pressure. That will cause the switch not to work. Also is the fan coming on when it calls for heat. If not check power at the board. You have two wires that go to the draftmotor. They should have 115 volts going to them. But try killing power to unit first. rus Keep in thuch.

That control board is several hundred dollars. If I may make a suggestion, take a jumper and when the inducer fan starts, jump out the pressure switch. If it starts, it's not the board but a bad switch, hose or blocked exhaust vent.
