5) If F Sensor has trouble
Bad contact of connector/ insert correctly
Are MAIN PCB
Connector CN30 to CN75
inserted correctly?
Is F Sensor
unit normal?
Is the voltage between
MAIN PCB Connector CN30#3(Red) to
CN1#3(Black) normal?
Is the input voltage of
IC01 MICOM #52 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
