    Usually when they are stuck open it means that the pressure switch is defective OR some other component has failed to cause the pressure switch to close. To be sure these items will need to be tested by a professional on Site.

    I took the pressure switch off - disconnected the rubber tubing - and blew the switch out at the nossel. I took a small pipe cleaner and cleaned the nipple end out that the rubber tubing was attached to. Attached everything back and the furnace fired up.
