Recirculation Control Motor Test

Recirculation Control Motor Test

1. Disconnect the 7P connector from the recirculation control motor.

NOTICE
Incorrectly applying power and ground to the recirculation control motor will damage it. Follow the instructions carefully.


2. Connect battery power to terminal No. 1 of the recirculation control motor, and ground either terminal No. 5 or terminal No. 7. The recirculation control motor should run smoothly to the Fresh position (terminal No. 7 connected to ground), or the Recirculate position (terminal No. 5 connected to ground). Disconnect the ground immediately when the motor stops running.
NOTE: Do not reverse power and ground as this will damage the recirculation control motor.

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.
