Suburban SF-30F furnace won't turn on

My Suburban SF-30F furnace won't turn on. It will only click once. Has a Dometic Duo-Therm thermostat. A/C still comes on when moved to A/C but furnace won't come on. Can anybody help?

    The click means it's getting power. The next thing that is supposed to happen is the blower start. Since that's not happening it's probably either the control board or and blower.
    If it's the board, replace with a "Dino" brand board, they have twice the warranty the Suburban ones do
