What To Do

When the sensor failure and the compressor will be running like this—if 
the potentiometer (thermostat) setting below 3 position, the compressor 
will be running 20 minutes and then stop 30 minutes, if the 
potentiometer (thermostat) setting more than 3 position, the compressor 
will be running 30 minutes and then stop 20 minutes. If find the 
compressor work like above situation, it mean the sensor failure and 
need open the back of refrigerator and change sensor of refrigerator 
evaporator 

open the cover board of air duct in freezer room, check the fan if it no 
running, then measure the voltage between the red wire and black wire 
of fan, if the voltage is 12V,the the fan motor is failure and replace it 
with a new one

disconnect power, and let the ice defrost and inspect the water if it is 
flow through the drainpipe, if could not flow out, check if it contain 
impurity and clean the drainpipe

check the fuse if it is melt or not. If the fuse is melt, it mean that the 
sensor failure or PCB failure, need change the sensor or PCB.

inspecting the CN4 defrost heater two connector.If the heater is OK then 
it must be PCB failure and change the PCB.

inspect the potentiometer (thermostat), and measure the resistance value 
by adjusting the potentiometer (thermostat), if the resistance value no 
change by adjusting the potentiometer (thermostat),

Fan no work

No defrost.Freezer room 
temperature no enough cold and 
refrigerator room OK and open 
the cover board of are duct and 
find ice formation on evaporator

the temperature of freezer and 

refrigerator are no enough cold 

and the temperature no change by 

adjusting the potentiometer 

(thermostat) 

the the fan motor is failure and replace it 
with a new one

the drainpipe contain impurity

the sensor failure or PCB failure

the defrost heater is break or PCB failure

the potentiometer failure

the sensor failure
