6-1. If the trouble is detected by self-diagnosis
6. Self Diagnosis & Trouble Shooting
To do list
Start
Is MAIN PCB Connector
CN90 inserted correctly?
Is ICE Maker Sensor
unit normal?
YES
Bad contact of connector/
insert correctly
NO
YES
NO
• The error of sensor will be displayed on the front of display.
when the error of sensor is detected at initial power ON, the appliance will not operated and display of
abnormal sensor part will blink.
• The appliance will not stop operating when the error of sensor is detected during operation of the appliance.
But normal freezing might be not operated if the appliance is operated by the emergency operation mode.
You would better to check the appliance according to the self-diagnosis of the manual.
1) If ICE Maker(R) Sensor has troubled
Is the voltage between
MAIN PCB Connector
CN90 - "1"(Brown) and J23
JUMMPER normal?
NO (0.6V > Measurement < 4.6V)
Sensor MICOM/Connector number
ICE
Maker
Connector CN90-"1"(Brown)
and J23 JUMMPER PCB
typical Ground
Voltage measured between 4.6V ~ 0.6V.
Replace the temperature
