Verify Before Replacing Parts
- Confirm the exact Daikin model family and split/ multi split context before acting on a generic code description.
- Start with the exact model documentation and verify the full operating sequence before replacing parts, particularly around broken wires in, short circuit of, or disconnection of connectors from the fan motor harne….
- Use the listed causes as branches to confirm or eliminate with measurements, not assumptions — defective fan motor is a reasonable second branch.
- After the correction, run the system long enough to confirm the split/ multi split fault does not return under normal load.
