Remove the air duct.

Step 4

Unplug the electrical wires.

Step 5

Disconnect the terminal of potentiometer.

Step 6

Remove the UI film.

Step 7

Remove PCB box from air duct.
a) Use 2 mm slot screw driver to create a gap in front side.

b) Insert a steel ruler to even the gap.

c) Pull the PCB box out.

Step 8

Disassemble PCB box.
a)Prize off the buckle;
b) Remove the cover;

c) Disconnect the terminals;
d) Unscrew and remove the PCB;

CHECK AND TEST 2

Step 1

Reconenct all wires for fan, LED, heater, sensor, compressor etc..

Step 2

The terminal is not pushed into final
position: insert again to make sure that
connections are good.

Step 3

Check if terminal is filled with foam: use tweezers to pick foam out and
insert the terminal into position again.

Step 4

Power on the appliance and open freezer to
check if fan is blowing or not.

DIAGNOSIS 1


CHECK AND TEST 3

Step 1

Turn power output of
transformer to DC 12V

Step 2

Supply power from terminal in PCB area.

DIAGNOSIS 1


PROCEDURE 2


Step 1

Remove freezer shelf. 

Step 2

Lever 2 screw covers off. 

Step 3

Unscrew 2 screws. 

Step 4

Remove air duct:

a. Hold the decorative cover of air duct;

Pull air duct out; 

b. Disconnect the terminal of fan motor;  

c. Take air duct away. 


PROCEDURE 3

Step 1

Cut wire off from broken area. 

Step 2

Peel off the sleeves.

Step 3

Check to ensure proper wire order and connect them. 

Step 4

Tin soldering.

Step 5

Cover connection with electrical tape. 

CHECK AND TEST 4

Step 1

Set output of transformer to DC 12V to test fan from the terminal behind freezer air duct. 

DIAGNOSIS 5

CHECK AND TEST  5

Step 1

Check if the terminal is filled with foam.
If so, use tweezers to remove foam.

Step 2

Check if wire order in foam is right or not:
a. Set multimeter to resistance gear;

Step 3

b. Put detector into one end of wires in PCB
area.

c. Put another detector into end of wires
behind air duct.

DIAGNOSIS 7

PROCEDURE 4

Tip 1

Firstly insert the air duct into the slot at the
bottom.

Tip 2

When reinstalling air duct, move wires out
of the way to prevent crushing by air duct.

Tip 3

After pushing air duct back into position, you
should hear a clicking sound. If there is no
click, please repeatagain.

DIAGNOSIS 1

In freezer air duct area, check if terminal C is pushed into final position.

CHECK AND TEST 6

Step 1

Open the freezer and put your hand to freezer to feel if the fan is running.
