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
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.
** Measuring point of resistance value according to Sensor
**
Flex : CN30 ”9” ↔ CN76 ”1” measuring resistance value
** 0Ω: Short trouble / Ω∞: Open trouble
Sensor MICOM/Connector number
Voltage measured between 4.6V ~ 0.6V.
Measuring voltage of IC01 MICOM #87,
CN30-"9"(Yellow)and J23 JUMMPER
from PCB typical Ground part are similar.
→ Check the measure on the voltage of Resistance, R314
due to the SMD MICOM

Checking method of PANTRY Sensor resistance
CN30-"9"(Yellow) ↔ CN76-”1” (Gray)
- Compare the temperature table after measurement.
