Check to see if terminal is full of foam.
If yes, use tweezers to remove foam.
Step 2
Ensure terminals behind freezer air duct are properly inserted.
Step 3
Connect terminals with mainboard.
Step 4
Press Freezer Temp. button along with Mode button for 5 sec, “0” flashes in freezer temperature area.
Step 5
Press Freezer Temperature button, 1 and 3 will appear in freezer temperature area.
Step 6
When 3 appears, remove finger and select manual defrost.
DIAGNOSIS 2
CHECK AND TEST 3
Step 1

DIAGNOSIS 5
PROCEDURE 3
Step 1
Disconnect the terminals of heater.
Step 2
Use screwdriver to remove the heat conductor.
Step 3
Use 6mm cross-head screwdriver to unscrew on the right and left sides.
DIAGNOSIS 6
CHECK AND TEST 6
Step 1
Reconnect all terminals behind freezer air duct.
Step 2
Connect terminals with mainboard.
Step 3
Press Freezer Temp. button along with Mode button for 5 sec, “0” flashes in freezer temperature area.
Step 4
Press Freezer Temperature button, 1 and 3 will appear in freezer temperature area.
Step 5
When 3 appears, remove finger and select manual defrost.
DIAGNOSIS 6
PROCEDURE 4
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 the air duct into position there should be a clicking sound. If not, install again.
Tip 3
Check to see if there is a wide gap between air duct and cabinet.
IF SO, install air duct again.
Tip 4
Ensure that latches are properly inserted into cavities.
Tip 5
First, insert top of cover plate into the gap. Then, bend plate to insert the bottom. Lastly, snap middle into place.
