TROUBLESHOOTING

4-2-1. If the trouble is detected by self-diagnosis

-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 Sensor has trouble

ERROR Code

2¢ (-17¡ ) is recommended 38¢ (3¡ ) is recommended

Temperature table

**Measuring point of resistance value according to Sensor **

ICE MAKER : CN90#8 #4 measuring resistance value

** 0 : Short trouble /		: Open trouble
	Refer to circuit diagram in the manual
	Sensor MICOM/Connector number
ICE	Connector CN90#"4"(White) and
Maker	REG1 HEAT PCB common Ground

Voltage measured between 4.6V ~ 0.6V.

Measuring voltage of IC01 MICOM #78, CN90-"4"(White) and REG1, HEAT SINK from PCB typical Ground part are similar.

Check the measure on the SENSOR

MARKING #9(R901) due to the SMD MICOM

Checking method of ICE Maker Sensor resistance CN90# "8(Sky-blue) #4"(White)

- Compare the temperature table after the measure.

Start

Is MAIN PCB Connector	NO
CN90 inserted correctly?

	YES	NO	Bad contact of connector/ insert correctly
Is ICE Maker Sensor
unit normal?
	YES		Replace the ICE Maker
Is the voltage between		NO(0.6V > Measurement < 4.6V)
MAIN PCB ConnectorCN90#4
(White) and REG1
	YES	NO	Check the contact of PCB & Wire Terminal
Is input voltage of IC01
MICOM #78 normal?
	YES		Check the iced-solder, solder bridging,
			disturbed solder.
No trouble with PCB and temperature sensor.
Recheck the bad contact of the connection.

Checking method of ICE Maker Sensor voltage
- Measure the voltage of Sensor Check Point #9(IC01 MICOM #78)	typical PCB Ground
or CN90#4(White) REG1, HEAT SINK.
- Compare the temperature table after the measure. Measuring	REG1 HEAT-SINK
voltage of CN90#4(White) REG1, HEAT SINK are below.
