Step 1
Check for Child Lock icon
Check Ice Type/Water Key.
- If it is normal Inspect Tip 1-2 - If it is abnormal Inspect Step 2
Step 2
Check PANEL PBA WIRE HARNESS
Pin connection / switching - Inspection of 1~5Wire
Verify that the wires are in the correct order in the connector
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
Disassemble Main PBA Cover in the back
Inspect CN50 ~Wire Pin contacting and
switching - BLK / BRN / RED / ORG / YEL Verify that the wires are in
the correct order in the connector
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

Step 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 Check Auger Motor S/W that is on the top
of Left FF Section Door. - Inspect S/W with F room door closed
Using an Ohmmeter, check for0 with the S/W plunger pushed in by hand. If the door S/W has failed, the auger motor cannot work.
Step 3 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, Disassemble HINGE-UPP COVER, and check
the WIRE HARNESS connection - Inspect CONNECTOR No.7(BLU)+No.15(GRY)
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

Step 1
Remove the Ice bucket in ice room Remove 2 screws as shown
Remove the ice maker after pulling the
cooling pipe which is in the bottom of ice maker.
Step 2
Remove the Auger Motor and inspect the
Motor - Normal = GRY+BLK 3~5 - Defective = Open or 0
Step 3
Inspect the Main PBA + CONNECTOR Wire
- CN73 No.3(PNK) + CN70 No.5(RED)
Check Point Inspect the Auger Motor .

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

Step 1
Check the ICE Bucket for the presence of
ice.
If no ice, Enter After PANEL PBA Energy Saver+Alarm Key and touch LED Blink Fridge Key.
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
Inspect the YEL 16-PIN CONNECTOR
No.7(PNK) PIN contact/switching
Inspect Wire connector - No.7(PNK) + Main PBA CN 30 No.7(PNK)

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 Inspect the WATER HOSE bending
After disassemble the ASSY Valve, Purple 2
Pin Check - Normal part : 350~450 - Failure part : Open or 0
Check the housing No.1(PRP/BLK) + No.6(PRP/BLK)
Step 2
Check MAIN PBA + Liner CONNECTOR - Check CN70 No.5(RED)+CN73 No.1(PRP)
Check Point Inspect ICE MAKER Water supply problem

Step 2 (Inspect Comp operation)
Touch the Display Freezer for 3 sec to enter
Power Freeze. If compressor is not running due to satisfied settings or defrost cycle, it will take up to 8 minutes for compressor to operate again.
Check compressor operation. - If the Comp does not operate Check Step 3 - If the Comp operate well Check Step 6
