No Problem Possible Cause What To Do
the led failure
Open the refrigerator door and measure the voltage of CN3 in PCB,
if the voltage is zero then it mean the connecting wire failure and if
the voltage is 12V, it mean the led failure
the switch circuit is failure
If the CN3 voltage no 12 V and then check the CN4 voltage, if the
voltage CN4 no change by close and pen door, it mean the switch
circuit is failure.
no problem
the time between two starting is shorter than 12min; or refrigerator
room temperature is lower than the setting temperature, in this case, it
is no problem. You need waiting more time.
ompressor wire not right or compressor
damage
measure the voltage of compressor input connector, if it is OK then
check the starting and relay of compressor, also check the wire if it is
OK
6 product no any work the PCB failure
check the power by multimeter, if the input voltage is 220V-240, but
the led, compressor, fan, defrost heater are all no work, it mean the
PCB failure and need change a new PCB
PCB failure
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
measure the voltage between the CN2 red and black wire of PCB, if
the voltage is 12V, then check from the inner wire to fan connector
measure the voltage between the CN2 red and black wire of PCB,if
the voltage is zero, then the PCB failure and change a new PCB.
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
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
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
PCB had automatic self-examination: open the cover of PCB at the
back of product, plug in power and push the SW101 switch 3
seconds and the PCB begin automatic self-examination program,
then the led and compressor and fan and defrost heater all work two
