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 3 (COVER ICE ROUTE S/W failure)

When COVER open as failure of operation

Inspect the CONNECTOR OPEN

Inspect the MOTOR S/W TOUCH failure

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 .

Tip 1-3. Inspect ASSY Auger Motor operation

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

- 9/65 -

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)

Step 1 After disassemble the Ice Bucket and ice

maker Right side button on ice maker turns on for

2 sec

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

Tip 2-3. Inspect the Ice Valve operation

Tip 2-5. Inspect cooling power ( Must select Power Freeze first)

Do not turn off the power Measure Self-diagnostic test at TIP 2-4

Step 1 Touch Display Energy Saver+ Alarm Key at the same time for 8 sec. - Touch it until chime sound occurs after all LEDs blink If Error code appears Move TIP 2-4 - If there is no error code inspect Step 2

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

Step 3 (Inspect Comp Wire)

Check the problem on backside Unit left side

Step 4 (Comp single product operation failure)

Inspect rotating failure by Comp Coil breaking of wire - Check U(BLU), V(PRP), W(BLK) order Measure U-V, V-W, U-W, resistance

Normal : 11~12

Failure : Open

Step 5 (Comp Relay Failure)

Inspect Power sullying line - Comp Operation condition is normal : AC 100~125 V - Failure :Inspect Non Apply AC voltage)

Inspect comp OLP(Over Load Protection) - Normal : applying an electric current 0~1

- Failure: Open

Step 6 (Gas Leak failure)

When the temperature of Comp Working Comp-dome & Pipe-Condenser is not high repair sealedsystem because it is the failure of Gas Leak or Clogged

Step 4 (When the C-Fan failure)

When C-Fan operation or FG Signal failure, Compressor stops after 60min. Check the FG failure thorough self diagnosis even the Fan rotates.
