Connect battery power to terminal No. 1 of the recirculation control motor, and ground either terminal No. 5 or terminal No, 7. The motor should run smoothly to the Fresh position (terminal No. 5 connected to ground), or the Recirculate position (terminal No. 7 connected to ground). Disconnect battery power immediately when the motor stops running.
NOTE:
Do not reverse the power and ground connections, or leave the recirculation control motor connected to power and ground after it has stopped running. These actions will damage the motor.
