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
