At heat call furnace blower starts. The inducer motor does not start. I check the power at the control board going to the inducer motor not volts. Also checked the power at the inducer motor no volts.. Get the 3 red flashing led's indicating pressure switch.. Furnace still tries to cycle, 90 seconds later the inducer starts the furnace shuts off 3 short red flashes' 1 long red flash. Indicating inducer out of sequence.
I've checked all the wiring connections the one fuse on the control board. Reseated all the wire connection on the control board. Even jumped the pressure switch, same results as above. Checked thermostat wires connections also look good.. Jump the connection on the control board to bypass the thermostat - Same results. Any help would be appreciated.
