6. SELF DIAGNOSIS & TROUBLE SHOOTING
- 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 ofabnormal 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 troubled (check the other sensors in the same procedure)
Bad contact of connector/
insert correctly
Replace the temperature
sensor
Recheck the wire
connection part
Check the iced-solder, solder
bridging, disturbed solder.
Is MAIN PCB Connector
CN51 inserted correctly?
Is ICE Maker Sensor
Is ICE Maker Sensor
unit normal?
unit normal?
Is the voltage between
Is the voltage between
MAIN PCB Connector CN30 - "9"(WHT)
MAIN PCB Connector CN30 - "9"(WHT)
and "11" Pin from PCB normal?
and "11" Pin from PCB normal?
Is input voltage of
Is input voltage of
IC01 MICOM #13 normal?
IC01 MICOM #13 normal?
Start
NO
YES
YES
YES
YES
NO
NO
(0.6V > Measurement < 4.6V)
NO
No trouble with PCB and temperature sensor.
Recheck the bad contact of the connection.
ICE Maker :
Measuring voltage of IC01 MICOM #12, CN30-"9"(WHT) and "11"
Pin(CN30) from PCB typical Ground part are similar.
→ Check the measure on the voltage of Resistance, R905 DUE to
the SMD MICOM.
DATA1. Temperature table
** Measuring point of resistance value according to Sensor
** ICE MAKER : CN30 "9"
↔
"11" measuring resistance value
** 0Ω: Short trouble / Ω∞: Open trouble
Refer to circuit diagram in the manual
Sensor MICOM/Connector number
ICE MAKER : (F) CN30 "9"(WHT)
↔
"11"(WHT) measuring
resistance value
Voltage measured between 4.6V ~ 0.6V.
6-1) If the trouble is detected by self-diagnosis
ICE Maker
☞
Checking method of ICE Maker Sensor resistance
CN30 "9"(FLAT WHT)
↔
"11"(FLAT WHT) - Compare the temperature table after the measure.
PIN Number
☞
Checking method of ICE Maker Sensor resistance
- Measure the voltage of Resistance
ICE Maker : R905(IC01 MICOM #12) on PCB or CN30 "9"(WHT) and "11 Pin(CN90) from PCB
- Compare the temperature table after the measure.
Measuring voltage of ICE Maker : CN30 "9"(WHT) and "11" Pin(CN90) from PCB.
