No Problem Possible Cause 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

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.
Compressor 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 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 second and then
stop, all wore one time and then quit automatic self-examination
program, and the program will return the original setting. If the
automatic self-examination program no work, it mean the PCB failure
and need change it
