the port will be sucking in air, not blowing it out...did that make any difference or still dead in the water?
If it is still dead in the water take the two wires off the switch and jumper them together, if the furnace works then you may just have a faulty pressure switch that needs replaced
ok, are you sure the inducer motor is running, this is the blower for the exhaust, if it runs then by jumpering the pressure switch the next step is for the igniter to come on...
when you get a fault code 12, this is power on when call for heat is present and will run the blower motor that pushes the hot air into the house.
ok, just wanted to make sure...
turn the power to the furnace off and back on, after it gets done with its fault code 12, which should take about 90 seconds, the inducer motor will turn on, after it turns on then jump the two wires together and see what happens, leave them apart until the inducer motor turns on.
See what happens when you try this
