    wiring

    without pics, one would only guess what has been done. If you have a fan center, "T-T" goes there first. If it is going to the cad cell relay directly, the fan board has no idea there is a call for heat to run the blower. Pics and more info needed, for me anyway

    Proper Operation

    When limit opens on that furnace, it is supposed to drop 24 volts coming out of board to t-stat and blower should run non stop until limit closes. If it is not doing that, something is wrong. You will need a pro.
