CHECK AND TEST 1

Step 1

Unscrew cover of mainboard with a
Cross-head screwdriver.

Step 2

In PCB area, check if terminal is pushed into
final position.

Step 3

Step 3
In PCB, check to see if
terminal is filled with foam.


Step 4

If so, use tweezers to
remove it.

Step 5

In PCB area, use multimeter
to measure resistance value.

Step 6

Take note of the result.

Step 7

Measure the temperature
of freezer air duct, close to
sensor.

DIAGNOSIS 1



PROCEDURE 1



Step 1

Remove the drawers.

Step 2

Remove the glass partition.

Step 3

Remove the 3 screw
covers.

Step 4

Remove the 3 screws.


Step 5

Pull air duct out.

Step 6
Disconnect the terminal
of fan motor.

Step 7

Remove the air duct.

CHECK AND TEST 2

Step 1
Check if terminal is inserted to final position.
If not, please re-insert it to final position.


Step 2

Check if sensor is fix to correct position, as
showing in picture. If not, correct it.

Step 3

Check if wire of defrost
sensor is broken.
IF YES, REPLACE IT
WITH A NEW ONE.

Step 4

Disconnect terminal of
defrost temp. sensor.

Step 5

Check if the terminal is stuffed with foam.
If so, use tweezers to smash it and remove.

Step 6

Measure resistance of defrost temp. sensor
from terminal in freezer, and take note of it.

Step 7

Measure the temperature
of defrost temp. sensor.

DIAGNOSIS 2

PROCEDURE 2


Tip 1
When reassembling the air duct, move wires to prevent crushing with
edge of air duct.

Tip 2
After pushing air duct
into position, it should
make a click sound. If no
click is heard, do it again.

Tip 3
Check to see if there is
a large gap between air
duct and cabinet.
If there is, re-install
air duct again.

DIAGNOSIS 3


CHECK AND TEST 3

Step 1

Set multimeter to
resistance gear.

Step 2

Use a wire to connect
the terminals in PCB
area and measure the
resistance in foam side
(as shown in photo).

DIAGNOSIS 4


PROCEDURE 3


Step 1

Push a 6mm sucker
onto display and turn
the knob to strengthen
suction force.

Step 2

Wrap a belt around knob
to make it easier to pull
out of display board.
Tips for installing
display.

Tip 1
After connecting
terminal, please use tape
to fasten wires to avoid
crushing with cover.

Tip 2
After putting display
into cavity, press edge
until you hear a clicking
sound, this means the
board is pushed into final
position.
Tip 3
Please press all buttons
on display board to make
sure it works well.

PROCEDURE 4


Step 1

Prize off the cover on
door cap.

Step 2

Remove the screws (in
total 2).

Step 3

Pull out the plastic;


Step 4

Disconnect the terminal
for display panel.

Step 5

Remove tape.

Step 6

Push the display away
from the corner.

board.
Follow tips carefully

Tip 1
Please press all buttons
on display board to
check if it works well or
not. Make sure words
and icons are clear

Tip 2

If not, disassemble it and put tape onto the point indicated by red circle.
