Disclaimer: This information is for general reference. Error codes can vary by model and production year. Always refer to your machine's specific manual and the information printed on the unit itself.
Potential Causes & Solutions
- Defective swing flap motor.
- Defective indoor unit PCB.
- Defective connection cable.
- Defective airflow direction adjusting flap-cam.
Verify Before Replacing Parts
- Confirm the exact Daikin model family and skyair context before acting on a generic code description.
- Confirm filter condition, blower operation, and coil cleanliness before replacing any controls.
- Measure airflow-related readings that match the symptom, such as temperature split or static pressure.
- After the correction, run the system long enough to confirm the code does not return under normal load.
Field Signals to Confirm
What usually confirms it
Weak airflow, abnormal temperature split, or repeated protective trips tied to blower performance.
What can fool you
Charge and control faults often look similar until airflow and coil condition are verified first.
When to Escalate the Call
- The code returns after airflow and cleanliness checks are corrected.
- You find evidence of duct or static issues that require a larger system review.
