SAFETY PRECAUTIONS
Please read the followings before servicing your appliance.
1. Check if an electric leakage occurs in the set.
2. To prevent electric shock, unplug prior to servicing.
3. In case of testing with power on, wear rubber gloves
to prevent electric shock.
4. If you use any appliances, check regular current,
voltage and capacity.
5. Don't touch metal products in cold freezer with wet
hand. It may cause frostbite.
6. Prevent water flowing to electric elements in
mechanical parts.
7. When sloping the set, remove any materials on the
set, especially thin plate type. (ex.: glass shelf or
books.)
8. When servicing evaporator part, wear cotton gloves
without fail. It is to prevent wound by sharp fin of
evaporator.
9. Leave a breakage of refrigerating cycle to a heavy
service center. The gas in cycle inside may soil
ambient air.

Chec
k to assure that the Wine Chiller is level.
The Wine Chiller seems to make too much noise.
The rattl
ing noise may come from the flow of the refrigerant,
which is normal.
As each cycle ends, you may hear gurgling
sounds caused by the flow of refrigerant in your
Wine Chiller.
Contraction and expansion of the inside walls may cause
popping and crackling noises.
The Wine Chiller is not level.
The door wil

The Wine Chiller is
not level.
The door was reversed and not properly installed. The gasket is
dirty.
The shelves are out of position.
Display error code “E1”
The air sensor is open circuit failed. Connection main control
PCB is with white color wires. Check the circuit, if it is normal,
the sensor need to be replaced.
Dis

The air sensor is short circuit failed. Connection main control
PCB is with white color wires. Check the circuit, if it is normal,
the sensor need to be replaced.
Dis
play error code “E3”.
The defrost sensor is open circuit failed. Connection main
control PCB is with red color wires. Check the circuit, if it is
normal, the sensor need to be replaced.
Dis
play error code “E4”.
The defrost sensor is short circuit failed. Connection main
control PCB is with red color wires. Check the circuit, if it is
