Defective fan inverter unit

Verify Before Replacing Parts

  1. Confirm the exact Daikin model family and chiller context before acting on a generic code description.
  2. Confirm board LEDs, wiring polarity, and model compatibility before replacing control boards — this Daikin fault points at defective fan inverter unit.
  3. Check for intermittent communication faults caused by connectors, moisture, or damaged harnesses, and rule out the next candidate on the list.
  4. After the correction, run the system long enough to confirm the chiller fault does not return under normal load.
