Malfunction of humidity sensor system

All Recorded Causes

Defective humidity sensor Defective connector contact

Verify Before Replacing Parts

  1. Confirm the exact Daikin model family and skyair context before acting on a generic code description.
  2. Verify the sensor or thermistor reading against the expected range for the current operating condition, keeping in mind that defective humidity sensor.
  3. 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.
  4. After the correction, run the system long enough to confirm the skyair fault does not return under normal load.
