CHECK AND TEST 1
Step 1
Unscrew cover of mainboard with a Cross-head screwdriver.
Step 2
In mainboard area, check if terminal is pushed into proper final position.
Step 3
Set multimeter to resistance gear.
Step 4
Measure resistance of fridge temp. sensor from terminal in PCB area.
Step 5
Take note of value.
Step 6
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
Step 1
Remove crispers.
Step 2
Remove shelves.
Step 3
Loosen the decorative plate and remove.
Step 4
Remove the screw covers on the air duct with slotted screw driver.
Step 5
Unscrew the screws (total of three) with Cross-head screw driver.
Step 6
Lift the air duct up slightly and pull it out.
CHECK AND TEST 2
Step 1
Check if terminal is
properly inserted to final
position.
If not, reinsert it.
Step 2
Check if wires of fridge temp. sensor are damaged or not.
PROCEDURE 2
Step 1
Cut wire off.
Step 2
Peel off the sleeves.
Step 3
Check to ensure proper wire order and reconnect them.
Step 4
Tin soldering.
Step 5
Cover connecting point with electrical tape.
CHECK AND TEST 3
Step 1
Disconnect terminal of fridge temp. sensor.
Step 2
Measure resistance of fridge sensor from terminal in fridge air duct cover.
Step 3
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
Step 1
Release the clasp.
Step 2
Remove the foam air duct.
Step 3
Remove tape.
Step 4
Remove the broken sensor, and replace it with a new one.
PROCEDURE 3
Tip 1
Attach the sensor properly onto the air duct cover as shown in picture on right.
Tip 2
Make sure the sealing sponge is in good condition.
Tip 3
Make sure back cover of the air duct is not broken.
Tip 4
Make sure chiller temperature controller is installed in correct position.
CHECK AND TEST 4
Step 1
Set multimeter to resistance gear.
Step 2
Put one detector into one end of wires in PCB area, and another detector into one end of wires in fridge air duct cover.
PROCEDURE 4
Tip 1
Push terminals into final position, and then move wires onto cavity to avoid crushing wires with edge of air duct.
Tip 2
When reinstalling the air duct, first put the positive end of buckle (on the bottom) into the negative end.
Tip 3
Later, fasten the buckles on the top with same method.
CHECK AND TEST 5
Step 1
After complete procedures
above, follow procedures to conduct performance test.
DIAGNOSIS 5
