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

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

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.
