Step 1
①Check for “Child Lock” icon
②Check “Ice Type/Water” Key.
- If it is normalInspect “Tip 1-2”
- If it is abnormalInspect Step 2
Step 2
①Check PANEL PBA WIRE HARNESS
Pin connection / switching
- Inspection of 1~5Wire
Verify that the wires are in
the correct order in the connector
①Disassemble 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
①Disassemble 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
①If 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
①Push 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
①Check 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
①Disassemble 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,
①Disassemble HINGE-UPP COVER, and check
the WIRE HARNESS connection
- Inspect CONNECTOR
No.7(BLU)+No.15(GRY)
②Inspect 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

- 6/65 -
Step 3 (COVER ICE ROUTE S/W failure)
①When COVER open as failure of operation
②Inspect the CONNECTOR OPEN
③Inspect the MOTOR S/W TOUCH failure
- Rotate continuously when both 2 S/W are
not pushed
④Inspect BLUE / WHITE S/W exchanging
⑤Replace ASSY CASE-LEVER DISP .

Step 1
①Remove the Ice bucket
in ice room
①Remove 2 screws as shown
②Remove the ice maker after pulling the
cooling pipe which is in the bottom of ice
maker.
Step 2
①Remove the Auger Motor and inspect the
Motor
- Normal = GRY+BLK 3~5 Ω
- Defective = Open or 0 Ω
Step 3
①Inspect 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

Step 1
①Select 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 2-
4
Step 2 (Connection problem-Hose kinked)
①Inspect connection between external tap and
the product
- Check if it is connected to water supply
- Check if the tap is closed.
②Check for kinked Water supply line
Step 3 (Piercing Valve )
①Check for water with piercing valve open and
supply hose disconnected.
(Piercing valves are not recommended)
Step 4 (Filter Case problem)
①Remove 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
①Minimum water supply pressure should be
20 PSI.
②If 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

Step 1
①Check the ICE Bucket for the presence of
ice.
②If no ice, Enter After PANEL PBA “Energy
Saver”+”Alarm” Key and touch LED Blink
“Fridge” Key.
③In 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
②Inspect 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
①After 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
①Inspect the WATER HOSE bending
②After disassemble the ASSY Valve, Purple 2
Pin Check
- Normal part : 350~450 Ω
- Failure part : Open or 0 Ω
③Check the housing No.1(PRP/BLK)
+ No.6(PRP/BLK)
Step 2
①Check 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
CN 70
