Verify Before Replacing Parts
- Confirm the exact Daikin model family and heat reclaim ventilator context before acting on a generic code description.
- Start with line voltage, low voltage, and board output checks in sequence so the fault is isolated cleanly — the data plate flags actuation of external protection device.
- Inspect connectors, relay outputs, and any recently replaced electrical parts for mismatch or loose fit, and verify defective output signal wiring.
- After the correction, run the system long enough to confirm the heat reclaim ventilator fault does not return under normal load.
