T o remove shelves in the freezing compartment

●First remove the icemaking molds. Tilt the shell up at front, then lift it up pull it out of the tracks.

T o remove shelves in the chilled compartment

●Lift up the cover, push the cover to the right until the mounting hook disengages, then disengage the other mounting hook and pull out the cover.

●Pull the shelf forward until it stops. Then lift it up and pull it out.

T o remove door bins

●While pushing the bin to the left, left it up to disengage.

T o remove shelves in the refrigerating compartment

●Hold the shelf by the front and pull it forward of the rack.

T o remove storage drawers and covers

●Lift up to remove the cover. Pull the drawer out then lifting it up.

● 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

Check for the abnormalities

No

No No

No

Yes

10-2 Defrosting mechanism does not work

－13－

SR-21/24 NME(WME)

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.

●Tightly cover stored frozen food.

●Destribute food evenly in the comparment

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.
