4) If R DEF Sensor has trouble
Bad contact of connector/ insert correctly
Is MAIN PCB
Connector CN30 and CN76 inserted
correctly?
Is R DEF Sensor
unit normal?
Is the input voltage between
MAIN PCB Connector CN30-”8”(Skyblue)
and J23 JUMMPER normal?
Is the input voltage of IC01
MICOM # 86 normal?
Start
NO
YES
YES
YES
YES
Replace the temperature sensor
NO
Recheck the wire connection part
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 **
R-DEF : CN30-"8" ↔ 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 #86
CN30-"8"(Sky-blue) and J23 JUMMPER from
PCB typical Ground part are similar.
→ Check the measure on the voltage of Resistance R313
due to the SMD MICOM

Checking method of R Sensor resistance CN30-
"8"(Sky-blue)
↔
CN76-"1"(Gray)
- Compare the temperature table after
measurement.
