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
final position.
IF NOT, reconnect
it to make sure that
connections are good.
Step 3
Check if wire order is right, or if terminal is filled with foam.
Step 4
If terminal is filled with foam: use tweezers to pick foam out and insert the terminal into position again.
DIAGNOSIS 1
CHECK AND TEST 2
Step 1
Turn power output of transformer to DC 12V.
Step 2
Supply power from
terminal in PCB area.
Step 3
Put your hand near outlet
of freezer air duct to feel
if fan is blowing or not.
DIAGNOSIS 2
PROCEDURE 1
Step 1
Remove the drawers
Step 2
Remove the glass
partition.
Step 3
Remove the 3 screw
covers.
Step 4
Remove the 3 screws.
Step 5
Pull air duct out.
Step 6
Disconnect the terminal of fan motor.
Step 7
Remove the air duct.
CHECK AND TEST 3
Step 1
In duct area, check if terminal is pushed into final position. If not, reconnect it.
Step 2
Check whether terminal
is filled with foam.
If yes, please use tweezers to clean and remove the foam, and reconnect it again.
DIAGNOSIS 3
CHECK AND TEST 4
Step 1
Check if wires of fan motor are damaged or not.
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 5
Step 1
Set output of transformer to DC 12V to test fan from the terminal behind the air duct.
DIAGNOSIS 4
Note
CHECK AND TEST 6
Step 1
Set multimeter to resistance gear.
Step 2
Put one detector into end of wires in PCB area, and another detector into end of wires behind air duct.
DIAGNOSIS 5
Note
PROCEDURE 3
Tip 1
When reassembling the
air duct, move wires to
prevent crushing with
edge of air duct.
Tip 2
After pushing air duct
into position, it should
make a click sound. If no
click is heard, do it again.
Tip 3
Check to see if there is
a large gap between air
duct and cabinet.
If there is, re-install air duct again.
