CHECK AND TEST 1
Unscrew cover of mainboard with a Cross-head screwdriver.
In mainboard area, check if terminal is inserted to final position.
If not, reinserted to final position.
Set multimeter to resistance gear.
Test resistance of sensor from terminal in PCB area.
Take note of value.
Measure the temperature of freezer temp. sensor.
Find out standard resistance of freezer temperature sensor under measured temperature in Resistance Chart for Sensor.
DIAGNOSIS 1
PROCEDURE 1
Remove temp. sensor cover.
Cut down the head of temp. sensor.
Prepare a new temp. sensor and cut down the head.
Peel off the sleeves.
Check to ensure proper wire order and reconnect them.
Tin soldering.
Cover connecting point with electrical tape.
Install temp. sensor cover.
CHECK AND TEST 2
Test resistance of sensor from terminal in PCB area.
Take note of value.
Measure the temperature of freezer temp. sensor.
Find out standard resistance of freezer temperature sensor under measured temperature in Resistance Chart for Sensor.
