Troubleshooting
1. Check the assembly condition of the sensor connector(CN43) on the indoor unit Main PCB and if not assembled, reassemble the
connector accurately.
2. Detach the room pipe sensor connector(CN43) and check the resistance between connector 3 and 4.
If the above data is not met, replace the room pipe sensor.
3. Assemble the room pipe sensor to PCB, plug in, and check the voltage of connector 3 and 4. If the resistance is below 0.5V or
over 4.9V, replace the indoor Main PCB. (short or disconnected in the PCB board)
