Detection
Refrigerant shortage detection I :
Refrigerant shortage is detected by checking the power consumption value and the compressor
running frequency.
Malfunction
Decision
Conditions
Refrigerant shortage detection I :
Power consumption < 4578 / 256 (W/Hz) × Compressor running frequency – 638 (W)
However, when the status of running frequency > 48 (Hz) is kept on for a certain time.
If a refrigerant shortage error takes place 4 times successively, the system is shut down. The
error counter is reset if this or any other error does not occur during the following 60-minute
compressor running time (total time).
Supposed
Causes
Refrigerant shortage (refrigerant leakage)

- Check no 4 conduct the followings to check the electronic expansion valve ev 1 check to see if the ev connector is correctly inserted in the pcb match the ev unit number and the connector number 2 turn the power off and on again and check to see if all the evs generate latching sound 3 if any of the evs does not generate latching sound in the above step 2 disconnect that connector and check the continuity using a tester check the continuity between the pins 1 6 and 3 6 and between the pins 2 5 and 4 5 if there is no continuity between the pins the ev coil is faulty 4 if no ev generates latching sound in the above step 2 the outdoor unit pcb is faulty 5 if the continuity is confirmed in the above step 3 mount a good coil which generated latching sound in the ev unit that did not generate latching sound and check to see if that ev generates latching sound 223
- Electronic expansion valve check 223
- If latching sound is generated the outdoor unit pcb is faulty 223
- If latching sound is not generated the ev unit is faulty 223
