TROUBLESHOOTING

- The error of sensor will be displayed on the front of display.

When the error of sensor is detected at initial power ON, 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 cooling 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.

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

1) If Ice Maker Sensor has trouble

Bad contact of connector /

Insert correctly

Is Main PCB

Connector CN90 inserted

correctly?

Is Ice Maker

Sensor unit normal?

Is the voltage between

Main PCB Connector CN90-#4(White) and

REG1, Heat Sink normal?

Is input

voltage of IC10 MICOM #51

normal?

Start

YES

Replace the Ice maker kit

Recheck the wire connection part

NO (0.6V > Measurement < 4.6V)

Check the Cold solder joint, hort,

solder touch.

No trouble with PCB and temperature sensor.

Recheck the bad contact of the connector.

** Measuring point of resistance value according to

Sensor **

Ice Maker : CN90 #3 → #4 measure the resistance value

** 0Ω : Short trouble / ∞Ω : Opentrouble

Sensor MICOM / Connector number

Voltage is measured between 4.6V ~ 0.6V

Voltage of IC10 MICOM #51 is same with the measuring

voltage of CN90-#4(White), REG1, & Heat Sink from

PCB common Ground part.

→ Check the measure on the MICOM Pin #51 or Sensor

Marking #6(R903).

☞ Checking method of Ice Maker Sensor resistance

CN90 #3(White ) ↔ #4(White)

- Compare with the temperature table after

measuring.
