9) If PANTRY Sensor has trouble
Bad contact of connector/ insert correctly
Is MAIN PCB
Connector CN30 and CN76 insert
correctly?
Is Pantry Sensor
normal?
Is the voltage between
MAIN PCB Connector CN30-"9"(Yellow)
and J23 JUMMPER normal?
Is the input voltage of IC01
MICOM Pin #87 normal?

YES
Replace temperature sensor
NO
Recheck the wiring connection
NO(0.6V > Measurement < 4.6V)
Check the iced-solder, solder
bridging, disturbed solder
NO
No trouble with PCB and temperature sensor.
Recheck the bad contact of the connection.
