New blower wont stop nothing else working

Hello I have a gas furnace Heil model nule100bg01. About a month ago we had a power outage and the ac stopped working looked to be the blower motor and capacitor, wouldn't move when put directly to 120v so I replaced it. The new blower wont turn off except when I kill the power and the control board does not seem to be getting power I have a backup control board I tried but didn't do anything. What should I be checking the transformer, limit switch or something I haven't thought of

some boards have a optional continuous fan connection energized all the time when there's no call for heating or cooling - check yours.

would need to see a schematic to advise further.

Welcome to the forums.

The wiring diagram off the blower door is always a major plus for us..... How-to-insert-pictures.

In your case..... with no red LED from the board..... you need to check the 24vAC transformer.
Don't forget the blower door safety switch. When the door is off.... everything is dead.
