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. If not, reinsert it to final position.
Note: the photos shown are just for example, they are not actual images of the product.
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 TemperatureResistance Chart for Sensor
DIAGNOSIS 1
PROCEDURE 1
Step 1
Remove crispers.
Step 2
Remove shelves.
Step 3
Remove the upper air duct.
a. Prize up and remove the decorative cover.
b. Prize up the buckle on the air duct with slotted screwdriver, then remove the upper air duct
CHECK AND TEST 2
Step 1
Check if wires of fridge temp. sensor are damaged or not. If yes, reconnect it.
Step 2
Cut off wires
Step 3
Measure the resistance of fridge sensor from terminal in fridge air duct cover and record the value.
DIAGNOSIS 3
PROCEDURE 2
Step 1
Cute 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.
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.
