CHECK AND TEST 1

Note

Step 1

Unscrew cover of mainboard with a
Cross-head screwdriver.

Step 2

Check if terminal in PCB
area is inserted to final
position.
If not, reinsert it to final
position.

Step 3

Set multimeter to
resistance gear.




Step 4

In PCB area, measure the
resistance of freezer temp.
sensor with a multimeter.

Step 5

Take note of value.

Step 6

Measure temperature
of freezer temp. sensor.
Use the measured
temperature to find the
standard resistance value
in Temperature-Resistance
Chart for Sensor.


DIAGNOSIS 1

PROCEDURE 1

Step 1

Unscrew cover of
mainboard with a
Cross-head screwdriver.

Step 2

Disconnect terminals.

Step 3

Unscrew the mainboard.

Step 4

Prize off the buckle to
remove mainboard.

Reverse steps above
to install a new
mainboard.

PROCEDURE 1

Step 1

Remove all shelves.



Step 2

Remove basket.

Step 3

Unscrew.

Step 5

Pull the buttom air duct
out.

Step 6

Disconnect the wires for
thermostat.

Step 7

Take bottom air duct
away.

CHECK AND TEST 2

Step 1

Check if the terminal
is inserted into final
position.

IF SO, RE-INSERT
THEM.

Step 2

Check if the terminal is
stuffed with foam.

IF SO, USE TWEEZERS
TO SMASH IT AND
REMOVE.

Step 3

Measure resistance of
freezer temp. sensor from
terminal in freezer air duct
cover.

Step 4

Measure temperature
of freezer temp. sensor.
Use the measured
temperature to find the
standard resistance
value in Temperature-
Resistance Chart for
Sensor.

DIAGNOSIS 2


PROCEDURE 2

Step 1

Disconnect terminals.

Step 2

Remove the aluminium
tape.

Step 3

Unscrew.

Step 4

Use slot screw driver to
push the buckle into,
then pull the upper air
duct out and take it
away.

PROCEDURE 3

Note


CHECK AND TEST 3

Step 1

Set multimeter to
resistance gear.

Step 2

Put detector into one
end of wires in PCB area.
Put another detector into
end of wires behind air
duct.

DIAGNOSIS 3


PROCEDURE 2

Tip 1

Make sure the sealing
sponges are in good
condition.

Tip 2

When reinstalling the air
duct, fasten the wires to
avoid crushing with air
duct.

Tip 3

Check to see if there is
a wide gap between air
duct and cabinet. If there
is, reinstall air duct.
