The pressure switch, open or closed depends on the induce fan motor. the switch could of failed. Try blowing into it, in and out. And or your induce fan motor is not blowing out the excessive heat out of the furnace properly. We provide repairs in the So Cal Area.

Not sure what you have for furnace so I can only offer generic info. Take a jumper wire with alligator clips on each end. Hook one end of jumper to pressure switch terminal but keep original wires on it as well. You will have to slide the original wire back enough to clip on the jumper. Slide the second wire back as well but do not connect the jumper yet. Tape the door safety switch closed if you have to to be able to have the furnace run. As the inducer or exhaust fan spins up to speed, take the unused end of the jumper and hook to the second terminal of the pressure switch. This will fool the circuit board and the igniter should start to glow or spark. If this works, look for any blockage of the air intake pipe, the exhaust pipe, water or ice in any of the hoses, dirty air filter or restriction of the inducer fan. Even a small leaf can collect moisture and grow in size as it ices up restricting the vacuum. As the furnace runs, check the hoses going to the pressure switch to see how much vacuum is being produced by the inducer. This is what closes the switch. If you apply a small amount of vacuum to the pressure switch, you should be able to feel and hear the switch close. If not, replace the pressure switch.
Hope this is some help. Please rate my answer!

Open pressure switch is when your vent motor comes on it has to get a certain vacuum pressure or it won't ignite furnace. There should be some little black hoses connected to vent motor and maybe into heat exchanger, running to these pressure switches. Pull hose off one end and make sure hoses are not kinked or some times if hoses have sag in them they can fill with water. Other causes are if venting is obstructed or pressure switch is defective, especially if it got moisture in it.
