Airflow Sensor Replacement

Procedure to replace the airflow sensor is as follows:

1.

Gently pull the sensor cover outward and rotate it by 75 degree.

Fig. 12. Removing the sensor cover

2.

Disconnect the electrical connector by gently pulling it away from the differential pressure sensor.

3.

Replace the airflow sensor.

Fig. 13. Replace the sensor

4.

Attach the electrical connector.

NOTE: Before closing the sensor cover, make sure to push the excess cable into the controller cavity. The sensor cover will

not snap into the controller if the cable is not tucked correctly.

5.

Close the cover.
