● Check the model, rated voltage, rated
current, operating temperature etc. of
the component.
When servicing the refrigera-tor,
completely remove dust or
foreign substances from the
housing,electric conne-ctions
and etc.
● This can proect against the risk of fire
hazard caused by tracking and short

●Cold air generated from the cooling
system is distribued to the freezing
compartment and the refrigeratung
compartment by the air circulation fan.
●In the freezing compartment, cold air is
distributed to the compartment as as
well as to the shelves from the cold air
exhaust port, food is frozen in the
freezing compartment by cold air
shower.
Cold air that comes out of the freezing
compartment is absorbed back to the
lower part fo the cooling system
through the suction port on the median
divider.
●In the refrigerating compartment, cold
air is distributed to the damper cover
through the medien divider.
coner through the median divider.
Cold air supplied to the damper cover
passes through the rotating blade and
evenly cools the refrigerating
comparment.
After cooling the refrigerating
compartment, cold air is absorbed to
the lower part of the cooling system
through the suction port the median
divider.

10.Troubleshooting method
－12－
SR-21/24 NME(WME)
10-1 The refrigerator does not operate
Is the interior light
on when the door switch is
pushed?
Does the compressor operate?
The compressor is operated for more
than 30 minutes and the refrigerator.
The compressor is defective
The freezing cycle has a problem
Make sure the refrigerator is plugged in
at the wall outled.
Make sure that
the thermometer in the freezer
compartment is electrcally
connected.
Chesk the defrost timer
Check the P.T.C relay
Check the overload relay
Check the condenser
The compressor is defective
Replace the defective part
If the fan operates when you push the
door switch, it is normal (Replace if it is
defective)
Replace the defective part
Check the electrical connection

10-3 Defrosting mechanism does not work
Check that the defrost
timer operates properly
Check the temperature fuse
Check the bimetal
thermometer
chect the defrost heater
Replace the defrost timer
Replace the defrst heater
Replace the bimetal thermometer
Replace the temperature fuse
Does the cooling fan operate?
Is too much
food stored in the freezer
compartment?
Is the freezer defrosted normally?
Is the door closed properly?
Is the door stopper hinge normal?
●Check the cooling fan motor
●Check the door swittch
●Defrost timer
●Temperature fuse/ Bimetal thermometer
●Defrost heater
●Check that the door gesket is properly
seled, check for the damaged gasket.
●Correct or readjust the door stopper
hinge
●Tightly cover stored ice cubes.

10-4 Trouble chesk for the cooling cycle
－14－
SR-21/24 NME(WME)
Moisture in the refrigerant
causes the malfunction.
Foreign substances
hamper the cooling cycle.
The comperssor is
defective
Too much refrigerant
Refrigerant leaks.
(Slight refrigerant leakage
causes partial cooling
with frost on the EVAP)
Replace the refrigerant
Locate the disturbed section
and make repairs
Replace the compressor
Replace the refrigerant
After welding the leaked
spot, replace the refrigerant
Symptom Cause Suggestions
●The EVAP cools down and warms again
●The condenser warms in proportin as the
EVAP cools,
●The process continues to repeat.
●The condenser is cold
●The EVAP is not cold
●The temperature of the comrressor is
high
●No difference in temperatures
detween suction pipe and discharge
pipe
●The temperature of the compressor
is maintained at room temperature.
●The EVAPdoes not cool down.
●Frost on the suction pipe
●The condenser is overheated.
●The refrigeration in the EVAP is not
effecient.
●The condenser is cold.
●The compressor surface temperature
is hogh.
●The refrigerator is not easily get
cooled.
