2) ICE Maker(FZ) Sensor has troubled
ERROR Code
Bad contact of connector/ insert correctly
Is MAIN PCB
Connector CN90 inserted
correctly?
Is ICE Maker(FZ)
sensor unit normal?
Is the voltage between
MAIN PCB Connector CN90-"9"(Red)
and REG1-GND normal?
Is input voltage of
IC01 MICOM #13 normal?
Start
NO
YES
YES
YES
YES
Replace the ICE Maker
NO
Check the contact of PCB &
Wire Terminal correctly.
NO(0.6V > Measurement < 4.6V)
Check the iced-solder, solder
bridging, disturbed solder.
Replace the PCB
-
This refrigerator has Dual Ice Maker,
so controlled two Ice Makers.
NO
No trouble with PCB and temperature sensor.
Recheck the bad contact of the connection.
