CHECK AND TEST 1
Step 1
Unscrew cover of mainboard with a Cross-head screwdriver.
Step 2
In mainboard area, check
if terminal is inserted to
final position.
If not, reinserted to final
position.
Step 3
Set multimeter to resistance gear.
Step 4
Test resistance of sensor from terminal in PCB area.
Step 5
Take note of value.
Step 6
Measure the temperature of fridge temp. sensor.
Find out standard resistance of fridge temperature sensor under measured temperature in Resistance Chart for Sensor.
DIAGNOSIS 1
PROCEDURE 1
Step 1
Remove temp. sensor cover.
Step 2
Cut down the head of temp. sensor.
Step 3
Prepare a new temp. sensor and cut down the head.
Step 4
Peel off the sleeves.
Step 5
Check to ensure proper wire order and reconnect them.
Step 6
Tin soldering.
Step 7
Cover connecting point with electrical tape.
Step 8
Install temp. sensor cover.
CHECK AND TEST 2
Step 1
Test resistance of sensor from terminal in PCB area.
Step 2
Take note of value.
Step 3
Measure the temperature of fridge temp. sensor.
Find out standard resistance of fridge temperature sensor under measured temperature in Resistance Chart of Sensor.
DIAGNOSIS 2
