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 fridge temp. sensor.
Find out standard resistance of fridge temperature sensor under measured temperature in Resistance Chart for Sensor.
DIAGNOSIS 1
PROCEDURE 1
Remove fridge temp. sensor cover.
Cut down the fridge temp. sensor.
Prepare a new fridge 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 fridge temp. sensor cover.
CHECK AND TEST 2
