TROUBLESHOOTING

-This refrigerator uses the BLDC Fan Motor. The BLDC Motor operates with DC 7~12V
-When there is defect, turn on the self-Diagnosis function and confirm the defect 
  before turning off the unit.

Start

Turn on Forced Operation.

FAN works normal.

Operation Temp / Stand-by

Replace Main PCB

◆ Expected Causes

① Defective Fan-Motor
② Contact error at wire connection
③ 

 

When the Fan Motor operates, check the input of 

the Motor Spinning Pulse.

No

Yes

No

No

Yes

No

Yes

Yes

COMP is running?

Is the temperature 

of the Ice Room good for the Fan to 

operate?

Voltage between MAIN 

PCB GND and CN76 #6

is measusred about DC8~12V ?

Does the voltage between 

MAIN PCB GND and CN76 #6 

repeat between DC8~12V 

and lower than DC 2V?

Ice Room Control Temperatture

Ice ON

-2.5℃

Ice Off

-14℃

Note

Pulse signal is generated at CN76 #7 when the Motor spins. 
This signal enters to MICOM and if there is no signal 
entering when the Motor spins, the Fan goes off and
works again in 10 seconds.
If there is still no signal entering, it repeats the above 
operation 4 more times.
If it keeps not sending the signal, the Motor operates in 10 
minutes. This is a function to overcome the case that there 
is a restriction in the Motor due to foreign substances 
around the Motor.

How to check the Ice Room-Fan Voltage

    - Ice Roon FAN : Voltage between CN76 #6 and GND shall be 
       DC8~12V.
    - After measuring it, check it again if the measurements is  
       different each other.
