6-1. If the trouble is detected by self-diagnosis
6. Self Diagnosis & Trouble Shooting
To do list
Start
Is MAIN PCB
Connector CN78 and CN76
inserted correctly?
Is Ice Room Sensor
unit normal?
YES
Bad contact of connector/
insert correctly
NO
YES
NO
7) If Ice Room Sensor has trouble
Is the voltage between
MAIN PCB Connector
CN78-"10"(Orange) and
J23 JUMMPER normal?
NO
(0.6V > Measurement < 4.6V)
Sensor MICOM/Connector number
Ice
Room
Connector CN78-"10"(Orange)
and J23 JUMMPER from PCB
Typical Ground
Voltage measured between 4.6V ~ 0.6V.
Replace temperature sensor
Check the wiring connection
Refer to circuit diagram in the manual
