    Furnace Trouble shooting
    I have an Coleman Evcon Furnace. Model #15020A the problem is I replaced the Inducer motor, and The furnace starts like normal but then the flames goes out after about a minute or two. The LED light says the Pressure switch is stuck open but it seems fine. I tried to replace the PC board but can't figure out where the wires go. Can someone help me?:(

    Test pressure switch for proper operation.
    Follow the wiring diagram for the correct wiring at the board.
