Please observe the following safety precautions in order to use safely and correctly the

refrigerator and to prevent accident and danger during repair.

1. Be care of an electric shock. Disconnect power cord from wall outlet and wait for more than three minutes before replacing PCB parts. Shut off the power whenever replacing and repairing electric components.

2. When connecting power cord, please wait for more than five minutes after power cord was disconnected from the wall outlet.

3. Please check if the power plug is pressed down by the refrigerator against the wall.

If the power plug was damaged, it may cause fire or electric shock.

4. If the wall outlet is over loaded, it may cause fire. Please use its own individual electrical outlet for th e refrig erat or.

5. Please make sure the outlet is properly earthed, particularly in wet or damp area.

6. Use standard electrical components when replacing them.

7. Make sure the hook is correctly engaged. Remove dust and foreign materials from the housing and connecting parts.

8. Do not fray, damage, machine, heavily bend, pull out or twist the power cord.

9. Please check the evidence of moisture intrusion in the electrical components. Replace the parts or mask it with insulation tapes if moisture intrusion was confirmed.

10. Do not touch the icemaker with hands or tools to confirm the operation of geared motor.

11. Do not let the customers repair, disassemble and reconstruct the refrigerator for them selves.

It may cause accident, electric shock, or fire.

12. Do not store flammable materials such as ether, benzene, alcohol, chemicals, gas, or medicine in the refrigerato r.

13. Do not put flower vase, cup, cosmetics, chemicals, etc., or contai ner with full of water

on the top of the refrigerator.

14. Do not put glass bottles with full of water into the freezer.

The contents shall freeze and break the glass bottles.

15. When you scrap the refrigerator, please disconnect the door gasket first and scrap it

where children are not accessible.

Set it right.

Change the Rubber absorber.

Attach a restrainer on the comp.

head to reduce vibration and

high frequency noise.

Change the compressor.

Remarks

● Compressor sound is somewhat normal because it works like a heart to circulate the refrigerant in the pipes during the refrigerator operation.

● Rattling or metallic touch sound of motor, piston of comp. can be heard when it starts or stops.

8-4. Operation Noise of Refrigerator

8-4-1. Comp. operation Noise

Refrigerator is leveled ?

Sound from Comp itself

or Vibration ?

Start

Attach an absorber gum

on the capillary tube.

Apply a gum on the

accumulator.

Apply a gum on the

accumulator.

Fasten the evaporator in F-

compartment tightly against

touching (liner) surfaces.

Explain refrigerator work

mechanism and sound to the

users or customers.

Remarks

● Water flowing sound, hiss or sizzling sound can make while refrigerant in the pipes is changing from

liquid to gas state when comp. starts or stops. It is normal to the refrigerator.

8-4-2. Refrigerant Flow Sound

Water flowing or hiss sounds

from the refrigerator ?

Refrigerant sound of hiss or

sizzling sound when comp. starts ?

Refrigerant sound of hiss or

sizzling when comp. stops ?

Any shaking sound from

F-compartment

when comp. works ?

Troubleshooting of Evaporator Sound

1. Hiss Sound from Capillary Tube

1) “I” tube is used to connect the capillary tube and evaporator. (2 welding points : ①, ②)

2. Sizzling Sound from Accumulator

3. Shaking or trembling Sound of Evaporator

1 2

2) When such a sound is made,

attach a absorber on the tube including 2 welding points.

Attach a absorber on point ③ (accumulator).

1) Check whether evaporator is fastened tight with the fasteners of ①, ②.

2) Insert a soft spacer (EPS) between left and right wall. Evaporator not to be shaken or trembled during refrigerator operation.

“I” tube

Remarks

● The fan is sending out cold air to circulate it through the compartments. When the air is touching the surface of louver or liner wall, such sound can make.

Start

Change the fan.

Set it right not to touch.

Set it right not to move.

Change the motor

assembly.

Explain to the customers

how fan is working to

circulate cold air in the

compartments.

8-4-3. Fan Noise

Fan is damaged

or transformed ?

Fan is touching

the surround ?

Fan-motor assembly

is moving or shaking ?

Motor has its own noise

or vibration when working ?

2) Check if fan motor and fan are hanged down. Fan working sound can be louder if they are not set right.

2. Any Touch Sound from Fan

Troubleshooting of Fan Noise

1. Fixing or Fastening of Fan Motor

1) Check if fan motor frame of the assembly is fastened tightly with screws to the liner wall. Unless it is tight, vibration of shaking can make.

1) Check if sealing sponge on the insulator touches the fan. If so, set it again not to touch it.

2) If any damage on the insulator around the fan rotation is found, set the fan motor assembly right not to touch it.

Remarks

● Refrigerant is erupting rapidly from the compressor to circulate pipes, so pipe shaking noise can make to some degree.

● In case compressor vibration is sent to a pipe directly, apply vibration absorber rubbers to welding points of the pipe and comp. or to a much bent point on the pipe.

Start

Separate the touching

pipes, if any.

Apply cushion material between

Comp. base and Tray drip.

Move or change the points of

vibration absorber rubbers on

the pipes to reduce the shaking.

Attach a absorber

on the comp. head.

9. COOLING CYCLE HEAVY REPAIR

1) Nitrogen only should be used when cleaning inside of cycle pipes inside and sealing.

2) Check leakage with an electronic leakage tester.

3) Be sure to use a pipe cutter when cutting pipes.

4) Be careful not the water let intrude into the inside of the cycle.

Others.

1) Weld under nitrogen atmosphere in order to prevent oxidation

inside a pipe. (Nitrogen pressure : 0.1~0.2 kg/cm2.)

Nitrogen blowing

welding.

1) Be sure to replace drier when repairing pipes

and injecting refrigerant.

Replacement of drier.

1) Remove retained refrigerant more than 5 minutes after turning off

a refrigerator. (If not, oil will leak inside.)

2) Remove retained refrigerant by cutting first high pressure side

(drier part) with a nipper and then cut low pressure side. (If the order is not observed, oil leak will happen.)

Removal of retained

refrigerant.

1) Use special parts and tools for R-134a or R-600aUse of tools.

9-3. Practical Work for Heavy Repair

* When replacing a drier:

Weld ①and② parts by blowing nitrogen (0.1~0.2kg/cm2) to high

pressure side after assembling a drier.

* When replacing a compressor:

Weld ③and④ parts by blowing nitrogen to the low pressure side. Note) For other parts, nitrogen blowing is not necessary because it does not produce oxidized scales inside pipe because of its short welding time.

2. Nitrogen blowing welding.

※ KEYPOINTING

Welding without nitrogen blowing produces oxidized scales inside a pipe, Which affect on performance and reliability of a product.

9-4. Standard Regulations for Heavy Repair

1) Observe the safety precautions for gas handling.

2) Use JIG (or wet towel) in order to prevent electric wires from burning during welding. (In order to prevent insulation break and accident.)

3) The inner case shall be melted and insulation material (polyurethane) shall be burnt if not cared during welding inner case parts.

4) The copper pipe shall be oxidized by overheating if not cared during welding.

5) Not allow the aluminum pipes to contact to copper pipes. (In order to prevent corrosion.)

6) Make sure that the inner diameter should not be distorted while cutting a capillary tube.

7) Be sure that a suction pipe and a filling tube should not be substituted each other during welding. ( High efficiency pump.)
