Connect battery power to the No. 1 terminal of the recirculation control motor, and ground the No. 5 or
No. 7 terminals; the recirculation control motor should run smoothly. To avoid damaging the
recirculation control motor, do not reverse power and ground. Disconnect the No. 5 or No. 7 terminals
from ground; the recirculation control motor should stop at Fresh (when the No. 7 terminal is
disconnected) or Recirculate (when the No. 5 terminal is disconnected). Don't cycle the recirculation
control motor for a long time.
NOTE:
Incorrectly applying power and ground to the recirculation control motor
