Air Mix Servomotor

Inspect Servo Motor Operation

1. With the positive (+) lead from the battery to terminal 8 and negative (-) lead to terminal 2, check that the lever moves smoothly from WARM to COOL.
2. With the positive (+) lead from the battery to terminal 2 and negative (-) lead to terminal 8, check that the lever moves smoothly from COOL to WARM.





3. While operating the servo motor from either points (a) or (b), measure the resistance values of terminals 13 and 15.
The resistance values from COOL to WARM will successively decrease.
If operation is not as specified, replace the servo motor.
Position Resistance (Ohms)
COOL 1,900 +/- 100
WARM 200 +/- 50
