TROUBLESHOOTING

4-2-3. If ICE Room Fan does not operate

-This refrigerator has BLDC FAN motor. BLDC motor is driven by DC7~12V.

-When COMP ON, normally operates with F-FAN motor.

-If there is any trouble, you should select the self-diagnostic function to check the trouble before power off.

-When pressing the ICE TEST S/W for a certain period of time (over 1.5sec), the function is accomplished. After beginning of TEST mode, Ice maker heater turns on for initial 2 minutes, if the

ice making temperature is below 0 .

- If it exceeds 0 , Ice maker heater turns on for initial 30 seconds.

- After Ice maker heater turns on for 30 seconds, it turns off and

then Ice maker motor turns on.

Operation

temperature/ready

Reference

CN76 #6 will generate the pulse signal when motor rotates. These signals will be input into MICOM.

Unless signals are not input during motor operating, will be ON 10seconds after fan OFF. But if signals are not still taken, the above operation will be retried four times more. If signals are not taken continuously, the motor will be restarted after 10 minutes. This function is against the case that motor movement would be restrained by foreign matters like ice.

Does DC7~12V alternate

with below DC2V between MAIN PCB REG1

Heater Sink and CN76-”2”(Black)?

Yes

Replace MAIN PCB

CN76-”6”(Pink)	REG1	Heater Sink

The voltage is variable due to pulse signal but measured about 2~3V with the Multi-Meter.

Predicted Cause

FAN-MOTOR troubles itself

Bad wiring connections.

Wrong Input of the fan motor rotation pulse

Checking method of Ice Room FAN Motor Voltage with the voltage between typical PCB Ground REG1 Heater Sink and Ice Room FAN ; CN76-”2”(Black) shall be less than DC 6~12V.

-Additional check if resistance values are different after measurement.
