5. Self-diagnosis Function
1)If the power is supplied to refrigerator, self-diagnosis function is carried out for 2 seconds
internally.
2)If there is no defect after self-diagnosis is carried out, it returns to normal operation.
3)If there is defect after self-diagnosis is carried out, defected area is indicated with the
corresponding display on the Table below by indicating Lamp on PCB, it does not start until all
defects are completely repaired.
4)When the refrigerator is repaired, check if it's done completely by turning power ON and OFF.
5)In order to check OPEN/SHORT function of SVC temperature sensor, carry out self-diagnosis
by turning power ON and OFF.
6)Display of Lamp Indicating Defects (Lamp On Time: 0.3sec., Lamp Off Time: 2sec.)
●
If there are more than one defect, corresponding display is shown in sequence.
<Example of Defect Indication>
①
When R-Room Sensor is defected, LAMP repeats one time of 0.3 second on, and then 2
seconds off.
➁
When R-Room Sensor and EXT Sensor are defected at the same time, LAMP repeats one
time of 0.3 second on, 2 seconds off, and then 3 times of 0.3 second on, 2 seconds off.
