Question about Heating & Cooling
After the thermostat was satisfied in the heating mode the blower motor kept running, check stat, blower, circuit board couldn't find cause.
First check your high limit switch find the white wire coming from your blower moter and unplug it hold down your door switch to see if your furnace will shut off if not replace it and your blower will run for ten to 20 min or until your heater has cooled down.

the pressure switch is closed before the draft motor closes it.the board is telling you that this is not right.pull the wire(either) off of the pressure switch to see if furnace tries to light.if it does,you should replace the pressure switch.
