- Compare the temperature table after the measure.
Start
Is MAIN PCB
Connector CN90 inserted
correctly?
YES
Is ICE Maker(FZ)
sensor unit normal?
YES
Is the voltage between
MAIN PCB Connector CN90-"9"(Red)
and J23 JUMMPER normal?
YES
Is input voltage of
IC01 MICOM #75 normal?
YES
No trouble with PCB and temperature sensor.
Recheck the bad contact of the connection.
☞ Checking method of ICE Maker Seneor
- Measure the voltage of Resistance R904(IC01 MICOM #75) or
CN90-"9"(Red) ↔ J23 JUMMPER.
- Compare the temperature table after the measure. Measuring
voltage of CN90-"9"(Red) ↔ J23 JUMMPER.

troublesHooting
- This refrigerator has Dual Ice Maker, so
controlled two Ice Makers.
NO
Bad contact of connector/ insert correctly
NO
Replace the ICE Maker
NO(0.6V > Measurement < 4.6V)
Check the contact of PCB & Wire Terminal
correctly.
NO
Check the iced-solder, solder bridging,
disturbed solder.
Replace the PCB
