Connector CN30 and CN76 insert
correctly?
Is Mid drawer Sensor
normal?
YES
Bad contact of connector/
insert correctly
NO
YES
NO
8) If PANTRY Sensor has trouble
Is the voltage between
MAIN PCB Connector
CN30-"9"(Yellow) and
J23 JUMMPER normal?
NO
(0.6V > Measurement < 4.6V)
Sensor MICOM/Connector number
Mid
drawer
Connector CN30-"9"(Yellow)
to J23 JUMMPER PCB
typical Ground
Voltage measured between 4.6V ~ 0.6V.
Replace temperature sensor
Recheck the wiring
connection
Refer to circuit diagram in the manual
