Goodman GPD075

Getting a pressure switch stuck closed code. Replaced switch, checked tube, flue etc. Tried jumping pressure switch wires and received a faulty flame sensor code (ignition would not start as well). Any suggestions?

Re: Goodman GPD075

I would check the inducer motor and make sure there is nothing inside the housing blocking the pressure switch port and also take a magnahelic guage and see what the W.C. is that it is pulling just to make sure it is running full RPM's. Remove and clean the flame sensor as well (if you haven't already). If all the above check ok, time to look at a control board.
