Recirculation Control Motor
Recirculation Control Motor Test
1. Disconnect the 7P connector from the recirculation control motor.
NOTE: Incorrectly applying power and ground to the recirculation control motor will damage it. Follow the instructions carefully.
2. Connect battery power to the No.1 terminal of the recirculation control motor, and ground the No.5 and 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 or Recirculate. Don't cycle the recirculation control motor for a long
time.
3. If the recirculation control motor does not run in step 2, remove it, then check the recirculation control linkage and doors for smooth movement.
-
If the linkage and doors move smoothly, replace the recirculation control motor.
-
If the linkage or doors stick or bind, repair them as needed.
