Bro just take the black wire from the blower and connect it to L1 on the board if the motor turns on then it’s the board if the motor doesn’t turn on it’s the blower boom done 25 seconds

What if you by pass the blower motor with 120 from line voltage ? Will it diagnose if the motor is bad ?

Most of the time call for G is a lower speed than heat or cool so none of them would receive voltage.

I also learned to put a spade connector where the line voltage comes in and plug your blower wire onto it and if it turns on you have a bad board

Just had this question the other day on an old furnace. I had 120 volts getting sent to motor for half a second then failed everytime I reset system.

take black wire off cooling and run it directly to power if it runs the board is bad, if you didn't have a board and want give some air get a 911 relay and run the fan through that connecting common and fan to the coil 24vlt side and power and high speed to the load side until you get a board

Could hook up to the EAC terminals (if 120v) for a temp fix if you didnt have the board
