DIAGNOSIS 1
PROCEDURE 2
Note
Air-back-to-freezer duct is covered by freezer air duct, you need to disassemble freezer air duct and remove evaporator to check.
Step 1
Disconnect the terminals for heater. Use screwdriver to remove the heat conductor (if there is one).
Step 2
Use 6mm cross-head driver to unscrew on left and right.
Step 3
Lift evaporator and heater up 20mm. The bottom of refrigerator must be higher than the edge of water trough.
WARNING:
be careful NOT to deform pipes in red square during above step.
Step 4
We can find the air-back- to-freezer air duct after removing evaporator integrated with heater.
CHECK AND TEST 2
Step 1
Use hair dryer to blow hot air into air-back-to- freezer duct.
Step 2
Put hand near freezer outlet to feel if hot air is coming out or not.
Step 3
Keep blowing hot air into the air-back-to-freezer duct for several minutes. If a lot of water flows from the outlet, the duct is blocked with ice.
DIAGNOSIS 2
PROCEDURE 3
Step 1
Insert L-shaped hook into duct to crush foam and blow it away with hair dryer.
CHECK AND TEST 3
Step 1
Use hair dryer to blow hot air into air-back-to- freezer duct.
Step 2
Put hand near freezer outlet to feel if hot air is coming out or not.
DIAGNOSIS 3
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 air duct into position, it should make a click sound. If no click is heard, do it again.
