    HVAV Blower Control
    My heating unit blower will not come on in the (Fan Auto Mode). I hear the
    Heater come on but after a few seconds it shuts off. I assume there is some
    Type of limiter that shuts it off due to the blower not turning. The blower
    Will work in the (Fan On Mode) so this tells me the blower is working
    Properly. What is preventing the blower from not working properly in
    The (Fan Auto Mode)?

    There is a item on most furnaces caller a fan limit control or a fan control. It is possible that the control is defective. Look at the sticky notes at the beginning of this board.
