    Furnace blower motor won't come on
    I have a Conquest furnace {1994}. The exhust fan comes on and then the burners. I can hear a "click" but the blower motor won't come on. I replaced the blower motor but to no avail. The burners will continue to burn until the safety switch tells it to turn off. What could it be?

    Arthur,
    There is probably a capacitor on or near (or at least connected to) the motor. If you didn't get a new one with your new blower motor, I'd be suspicious of that. Does the motor get hot? That would be a clue that it is trying to start, but can't.

    Best of luck,
    WallyH

    Defective relay or fan control depending upon what kind of conntrol system you have.

    A wiring diagram is located on the back side of the blower door
