1) Self-diagnosis with initial POWER ON
1-1) With POWER ON, it shall diagnose the status of temp SENSOR in a minute in MICOM internally for itself.
1-2) If inferior sensor is found after self-diagnosis, corresponding DISPLAY LED will be all off at the interval of
0.5 sec. and there will be no sound with LED ON.
1-3) In the state that inferior sensor is found and DISPLAY ICON is off, it only recognizes self-diagnosis KEY
(Press Ice Type KEY + FILTER RESET KEY(LIGHT KEY) for 8 sec.) and normal temp control will be on
hold.
1-4) On self-diagnosis ERROR, if inferior sensor is fixed or if you press ICE TYPE KEY + FILTER RESET
KEY(LIGHT KEY) for 8 sec., it will be canceled automatically.
2) Self-diagnosis during normal operation
2-1) When pressing “ ICE TYPE ” and “ FILTER RESET(LIGHT) ” KEYS simultaneously for 6 sec. in normal
operation of the fridge, temp set DISPLAY will be All ON/OFF for 2 sec. at the interval of 0.5 sec. and
when pressing “ ICE TYPE ” and “ FILTER RESET(LIGHT) ” KEYS simultaneously for 8 sec. including
TOGGLE for 2 sec., self-diagnosis will be selected.
2-2) At this point, “ SOUND ”shall be heard and it operates self-diagnosis.
2-3) When self-diagnosis operates, entire LED will be OFF and only relevant LED with malfunction will be ON
/ OFF repeatedly signifying defects. (Refer to the below self-diagnosis CHECK LIST)
2-4) When an ERROR occurs, it will be indicated for 30 sec. and restored to the normal status regardless of
maintenance.
