Testing furnace blower motor fan

[rvul]

I had a little flood and my suburban furnace got wet. I am trying to test the blower at this point. I have it on the bench. Question how do you by pass the board to test the blower with out the thermastate. Any other suggestions on this process is welcome. thanks for your time in advance.

You can jumper the 12+ vdc line to the T'stat line on the connector. This will energize the delay relay and in a few seconds the blower should start up. After running about 7 seconds the gas valve and igniter should be energized. Another way would be to remove motor leads and apply 12 vdc directly to the motor.

Welcome to the community! You have probably already done so; I would make sure the motor, including winding is completely dry of moisture before energizing.
