CHECK AND TEST 1

Step 1

Unscrew cover of mainboard with a Cross-head screwdriver. 

Step 2

In PCB area, check if terminal is pushed into final position. 

Step 3

In PCB, check to see if terminal is filled with foam.

Step 4

If so, use tweezers to remove it. 

Step 5

In PCB area, use multimeter to measure resistance value. 

Step 6

Take note of the result. 

Step 7

Measure the temperature of freezer air duct, close to sensor. 

DIAGNOSIS 1


PROCEDURE 1


Step 1

Remove freezer shelf. 

Step 2

Lever 2 screw covers off. 

Step 3

Unscrew 2 screws. 

Step 4

Remove air duct:

a. Hold the decorative cover of air duct;

b. Pull air duct out; 

c. Disconnect the terminal of fan motor; 

d. Remove freezer air duct. 

DIAGNOSIS 2


PROCEDURE 2


Step 1

Cut wire off from broken area. 

Step 2

Peel off the sleeves. 

Step 3

Check to ensure proper wire order and connect them. 

Step 4

Tin soldering.

Step 5

Cover connection with electrical tape. 

CHECK AND TEST 2

Step 1

Use a multimeter to measure the resistance value of defrosting temp. sensor from terminal located in freezer. 

Note

Insert the detectors into terminal and make sure connection is good. 

Step 2

Read the value. 

Step 3

Measure the temperature of sensor. 

DIAGNOSIS 3


CHECK AND TEST 3

Step 1

Check to see if the terminal is filled with foam. 

Step 2

If so, use tweezers to crush and remove foam.

Step 3

Make sure sensor is properly located by comparing with photo on right.

If sensor is not in same position as photo, fix it. 

Step 4

Connect the 2 ends in PCB area. 

DIAGNOSIS 4


PROCEDURE 3


Tip 1

When reinstalling air duct, move wires out of the way to prevent crushing by air duct. 

Tip 2

After pushing air duct back into position, you should hear a clicking sound. If there is no click, please repeat again. 

Tip 3

Check to see if there is a wide gap between air duct and cabinet.

If gap is large, re-install air duct.
