	Sensor MICOM/Connector number
Ice Room	Connector Cn31#3(Orange) to REG1
	HEAT-SINK PCB common Ground

Voltage measured between 4.6V ~ 0.6V.

Measuring voltage of IC01 MICOM #77,

CN30-"4"(Orange) and REG1, HEAT SINK from PCB

typical Ground part are similar.

Check the measure on the SENSOR MARKING #8(R308) due to the SMD MICOM

Start

Is MAIN PCB		NO
ConnectorCN31 and CN76
inserted correctly?
	YES
		NO	Bad contact of connector/ insert correctly
Is Ice Room Sensor
unit normal?
	YES		Replace temperature sensor
Is the voltage between		NO(0.6V > Measurement < 4.6V)
MAIN PCB Connector CN31#3 (Orange) and
REG1, HEAT SINK normal?
	YES		Check the contact of PCB & Wire
Is the input voltage of		NO	Terminal correctly.
IC01 MICOM #71 normal?
	YES		Check the iced-solder, solder bridging,
			disturbed solder. Replace the PCB
No trouble with PCB and temperature sensor.
Check the bad connections.

Checking Mehod of Ice Room Sensor voltage CN31-”3”(Orange) CN76-”1” (Gray)

-Compare with the temperature table after measurement.

Checking method of Ice Room Sensor voltage
- Measure the voltage of Sensor Check Point #8
(IC01 MICOM #71) on PCB or CN31#3(Orange) REG1, HEAT SINK	typical PCB Ground
- Compare the temperature table after measurement. Measuring
voltage of CN31#3(Orange) REG1, HEAT SINK are as below	REG1 HEAT-SINK
