CHECK AND TEST 1
Unscrew cover of mainboard with a Cross-head screwdriver.
In mainboard area, check if terminal is pushed into proper final position.
Set multimeter to resistance gear.
Measure resistance of fridge temp. sensor from terminal in PCB area.
Take note of value.
Measure the temperature of fridge temp. sensor. Use the measured temperature to find the standard resistance value in Temperature- Resistance Chart for Sensor.
DIAGNOSIS 1
PROCEDURE 1
Remove crispers.
Remove shelves.
Loosen the decorative plate and remove.
Remove the screw covers on the air duct with slotted screw driver.
Unscrew the screws (total of three) with Cross-head screw driver.
Lift the air duct up slightly and pull it out.
CHECK AND TEST 2
Check if terminal is properly inserted to final position.
If not, reinsert it.
Check if wires of fridge temp. sensor are damaged or not.
PROCEDURE 2
Cut wire off.
Peel off the sleeves.
Check to ensure proper wire order and reconnect them.
Tin soldering.
Cover connecting point with electrical tape.
CHECK AND TEST 3
Disconnect terminal of fridge temp. sensor.
Measure resistance of fridge sensor from terminal in fridge air duct cover.
Measure the temperature of fridge temp. sensor. Use the measured temperature to find the standard resistance value in Temperature- Resistance Chart for Sensor.
DIAGNOSIS 3
PROCEDURE 2
Release the clasp.
Remove the foam air duct.
Remove tape.
Remove the broken sensor, and replace it with a new one.
Reverse steps above to
reinstall the air duct.
Please pay attention to
bellow key points.
Fasten sensor properly on air duct cover, as shown in the picture on right.
Make sure the sealing sponge is in good condition.
Make sure back cover of the air duct is not broken.
Make sure chiller temperature controller is installed to correct position.
CHECK AND TEST 4
Set multimeter to resistance gear.
Put one detector into one end of wires in PCB area, and another detector into one end of wires in fridge air duct cover.
DIAGNOSIS 4
Push terminals into final position, and then move wires onto cavity to avoid crushing wires with edge of air duct.
When reinstalling the air duct, first put the positive end of buckle (on the bottom) into the negative end.
Later, fasten the buckles on the top with same method.
