Step 1

① Check for “Child Lock” icon

② Check “Ice Type/Water” Key.

- If it is normal Inspect “Tip 1-2”

- If it is abnormal Inspect Step 2

Step 2

① Check PANEL PBA WIRE HARNESS

Pin connection / switching

- Inspection of 1~5Wire

Verify that the wires are in

the correct order in the connector

① Disassemble the HINGE-UPP COVER, check

the WIRE HARNESS Pin connection/switching
connection and verify the correct sequence

- Inspect BLK / BRN / RED / ORG / YEL
Wire

Step 3

① Disassemble Main PBA Cover in the back

Inspect CN50 ①~⑤Wire Pin contacting and

switching

- BLK / BRN / RED / ORG / YEL Verify that
the wires are in

the correct order in the connector

① If there is no problem on all,

- Replace the PANEL PBA

Check Point

Check the “Ice Type/Water” Key selecting operation.

Tip 1-1. Inspect Display “Ice Type / Water” selecting

CN 50

Step 1

① Push the DISPENSER LEVER to check Auger

Motor rotating sound. Auger motor is in

the Ice Room.

- If No operation sound, go to Step 2
inspection

- If operation sound, go to Step 4

inspection

Step 2

① Check Auger Motor S/W that is on the top

of Left FF Section Door.

- Inspect S/W with F room door closed

② Using an Ohmmeter, check for“0Ω” with the

S/W plunger pushed in by hand.

※ If the door S/W has failed, the auger

motor cannot work.

Step 3

① Disassemble the Display and check the Micro

LED S/W, located at the back of the Lever.

※ (Check for broken or stuck switches)

When there is no problem found,

① Disassemble HINGE-UPP COVER, and check

the WIRE HARNESS connection

- Inspect CONNECTOR
No.7(BLU)+No.15(GRY)

② Inspect Main PBA Connector

- Inspect CN50 No.5(YEL) and No.7(BLU)
Wire

Check Point

Inspect the Dispenser Lever S/W operation.

Tip 1-2. Inspect Lever S/W & Auger Motor S/W operation

BLU

GRY

Step 3 (COVER ICE ROUTE S/W failure)

① When COVER open as failure of operation

② Inspect the CONNECTOR OPEN

③ Inspect the MOTOR S/W TOUCH failure

- Rotate continuously when both 2 S/W are
not pushed

④ Inspect BLUE / WHITE S/W exchanging

⑤ Replace ASSY CASE-LEVER DISP .

Step 1

① Remove the Ice bucket
in ice room

① Remove 2 screws as shown

② Remove the ice maker after pulling the

cooling pipe which is in the bottom of ice
maker.

Step 2

① Remove the Auger Motor and inspect the

Motor

- Normal = GRY+BLK 3~5 Ω

- Defective = Open or 0 Ω

Step 3

① Inspect the Main PBA + CONNECTOR Wire

- CN73 No.3(PNK) + CN70 No.5(RED)

Check Point

Inspect the Auger Motor .

Tip 1-3. Inspect ASSY Auger Motor operation

CN 73

- 8/65 -

Step 1

① Select Water, then check the water

dispensing when pressing lever.

- When there is no water dispensing Check
Step 2

- When the water is dispensing check TIP 2­4

Step 2 (Connection problem-Hose kinked)

① Inspect connection between external tap and

the product

- Check if it is connected to water supply

- Check if the tap is closed.

② Check for kinked Water supply line

Step 3 (Piercing Valve )

① Check for water with piercing valve open and

supply hose disconnected.

(Piercing valves are not recommended)

Step 4 (Filter Case problem)

① Remove Water Filter and check dispensing.

If water dispenses ,try a new filter. If
water does not dispense with new filter,
replace the Filter Case.

Step 5

① Minimum water supply pressure should be

20 PSI.

② If pressure is low due to external filter

(reverse osmosis) remove internal filter.

Check Point

Inspect Water supplying failure

Tip 2-1. Inspect water connection/supplying

※ Before first use and after filter replacement, dispense water for 3 min

Piercing Valve

- 9/65 -

Step 1

① Check the ICE Bucket for the presence of

ice.

② If no ice, Enter After PANEL PBA “Energy

Saver”+”Alarm” Key and touch LED Blink
“Fridge” Key.

③ In the case of FF-Display Yellow Blink

- Recognized Ice Bucket Full  Check STEP 2

- When there is no Blink  Check Tip 2-3

Step 2

① Inspect the “YEL 16-PIN” CONNECTOR

No.7(PNK) PIN contact/switching

② Inspect Wire connector

- No.7(PNK) + Main PBA CN 30 No.7(PNK)

Main PBA

Check Point

Inspect ice maker Water supply problem

Tip 2-2. Inspect Ice Full sensing failure

Step 1
① After disassemble the Ice Bucket and ice

maker

Right side button on ice maker turns on for

2 sec

① Takes Max “6 Min” (including Heating

time)

- When the water does not come Check
Step 2

- When the water come  Check TIP 2-5

Step 2

① Inspect the WATER HOSE bending

② After disassemble the ASSY Valve, Purple 2

Pin Check

- Normal part : 350~450 Ω

- Failure part : Open or 0 Ω

③ Check the housing No.1(PRP/BLK)

+ No.6(PRP/BLK)

Step 2

① Check MAIN PBA + Liner CONNECTOR

- Check CN70 No.5(RED)+CN73 No.1(PRP)

Check Point

Inspect ICE MAKER Water supply problem

Tip 2-3. Inspect the Ice Valve operation

CN 73
