Verify Before Replacing Parts

  1. Confirm the exact Daikin model family and vrv context before acting on a generic code description.
  2. Confirm filter condition, blower operation, and coil cleanliness before replacing any controls — start by ruling out whether defective swing flap motor.
  3. Measure airflow-related readings that match the symptom, such as temperature split or static pressure, and check whether defective indoor unit PCB.
  4. After the correction, run the system long enough to confirm the vrv fault does not return under normal load.
