    AC issue, outside unit working, blower fan not working
    Hi, newbie here.

    My AC is having issues: the outside unit is working, but the blower fan is not. So I tested it out with these findings:
    1. Normal condition: Ctrl - cool, Fan - auto, as stated above;
    2. Ctrl - off, Fan turned to on, fan is working (air coming out from vent);
    3. Then turned Ctrl to cool: AC unit starts working, but fan stopped, and no air coming from vent.
    4. For fear of coil freeze, I turned ctrl to off and left Fan at on for several hours.
    I then tried again by turning ctrl to cool, same issue. No change.

    Can somebody figure out what the issue is, furnace control board, AC unit control, evaporator coil, or?

    Thanks so much!
