CHECK AND TEST 1
Check if terminal in PCB
area is inserted to final
position.
If not, reinsert it to final
position.
Set multimeter to
resistance gear.
Step 4
In PCB area, measure the
resistance of freezer temp.
sensor with a multimeter.
Take note of value.
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
Prize off the buckle to
remove mainboard.
Reverse steps above
to install a new
mainboard.
PROCEDURE 1
Pull the buttom air duct
out.
Disconnect the wires for
thermostat.
Take bottom air duct
away.
CHECK AND TEST 2
Check if the terminal
is inserted into final
position.
IF SO, RE-INSERT
THEM.
Check if the terminal is
stuffed with foam.
IF SO, USE TWEEZERS
TO SMASH IT AND
REMOVE.
Measure resistance of
freezer temp. sensor from
terminal in freezer air duct
cover.
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
Remove the aluminium
tape.
Use slot screw driver to
push the buckle into,
then pull the upper air
duct out and take it
away.
PROCEDURE 3
CHECK AND TEST 3
Put detector into one
end of wires in PCB area.
Put another detector into
end of wires behind air
duct.
DIAGNOSIS 3
PROCEDURE 2
Make sure the sealing
sponges are in good
condition.
When reinstalling the air
duct, fasten the wires to
avoid crushing with air
duct.
Check to see if there is
a wide gap between air
duct and cabinet. If there
is, reinstall air duct.
