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),

Trouble shooting guide

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

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

Compressor no starting

PCB failure
