I have a Goodman GMP075-3 RevB. The fan for the exhast comes on but the starter does not heat up and the burners do not go on. Light blinks 3 times. This means the Venter Pressure switch vent is blocked. What does that mean? There is a rubber hose on the exhast fan that when I blow into it, I cannot get any air through. I do not know how to remove this from the fan.
