DIAGNOSIS 1


PROCEDURE 1


Step 1

Remove the freezer drawer.

Step 2

Remove the middle glass shelf located between upper and bottom freezer drawer compartments.

Step 3

Unscrew air duct

a. Check the freezer air duct to find the three screw covers.

Step 3

Measure the temperature of sensor.

 

Note


DIAGNOSIS 2

CHECK AND TEST 3

Step 1

Check to see if the terminal is full of foam.

IF SO, USE A TWEEZERS TO CRUSH AND REMOVE FOAM.

Step 2

Connect A to B with metal wire.

Use multimeter to measure the connection from D and D.

DIAGNOSIS 3


CHECK AND TEST 4

Step 1

Check to see if the terminal is pushed into final position.

Note


PROCEDURE 2


Tip 1

When re-installing the air duct, move the wires out of the way so that they won’t be crushed by air duct.

Tip 2

After pushing air duct into position, it should make a click sound. If no click is heard, do it again.

CHECK AND TEST 5

Step 1

Measure resistance of sensor from terminal in PCB area.

Step 2

Take note of resistance value.

 

Step 3

Measure the temperature of sensor.

Note


PROCEDURE 3


Step 1

Push a 6mm sucker onto display and turn the knob to strengthen suction force.

Step 2

Attach strap to knob to facilitate pulling out display board.

Tips for proper installation of display:

Tip 1

After connecting terminal, please tape wires in place to prevent crushing by the cover.

Tip 2

After inserting display into cavity, press edge until you hear a clicking sound, this means the board is pushed properly into final position.

Please press all buttons on display board to make sure display functions properly.

PROCEDURE 4


Step 1

Lever off the cover on door cap.

Step 2

Remove the screws (in total 2).

Step 3

Pull out the plastic;

Step 4

Disconnect the terminal for display panel.

Step 5

Remove tape.

Step 6

Push display out by the corner.

Reverse above steps to install display board.
Follow tips carefully:

Tip 1

Please press all buttons on display board to verify if it is working properly. Make sure all words and icons are clear.

PROCEDURE 5


Step 1

Unscrew cover of mainboard with a Cross- head screwdriver.

Step 2

Disconnect terminals.

Step 3

Unscrew the mainboard.

Step 4

Unfasten and remove mainboard.
