Verify Before Replacing Parts
- Confirm the exact Daikin model family and packaged context before acting on a generic code description.
- Verify the sensor or thermistor reading against the expected range for the current operating condition, keeping in mind that defective humidity sensor.
- Check the sensor harness and board connection before condemning the sensor itself; on Daikin units this is also where you'd confirm defective connector contact.
- After the correction, run the system long enough to confirm the packaged fault does not return under normal load.
