SAFETY PRECAUTIONS
Please read the followings beforeservicingyour 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.

3-2 SHELVES
(Models：RW54N1SSD)
The sides of the shelves are equipped with protective
stoppers which prevent bottles from falling from the shelves.
When removing / inserting the shelves from / into the rails,
lift one side of the shelf as shown in (Figure 2) and pull the
shelf out towards you, or push it in when inserting it, until
one side is securely seated on the rail.
Figure 2
(Model：RW46N1DSD)
To remove the shelves out of the rail, pull each shelf
approximately 1/3 out. Use a long flat screwdriver or similar
tool to press down the right plastic notch as shown in
Figure 3 and at the same time lift the left plastic notch as
shown in Figure 4. Then proceed to pull out the shelf slowly.
When inserting the shelves make sure the shelf sides fix
into the rails on both side and put to the end, and the shelf
should be move smooth, if it is not smooth, rework it
otherwise, the rails will be damaged.

Problem
Possible Cause
Appliance does not operate.
Not plugged in.
The appliance is turned off.
The circuit breaker tripped or a blown fuse.
Appliance is not cold enough.
Check the temperature control setting. External
environment may require a higher
setting.
The door is opened too often.
The door is not closed completely.
The door gasket does not seal properly.
NO cooling enough
The room temperature is hotter than normal.
A large amount of contents has been added to the wine chiller.
The door is opened too often.
The door is not closed completely.
The temperature control is not set correctly. The door
gasket does not seal properly.
The light does not work.
Not plugged in.
The circuit breaker tripped or a blown fuse. The bulb has
burned out.
The light button is “OFF”. Energy conservation button is on.
button is on.
Vibrations.
Check to assure that the Wine Chiller is level.
The Wine Chiller seems to make too much noise.
The rattling 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 will not close properly.
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 “E3”or “E4”.
(Models：RW54N1SSD):The defrost sensor is failed.
Display error code “E7”or “E8”.
(Models：RW46N1DSD):The lower zone sensor is failed.
Display error code “E0”or “E1”.
(Models：RW54N1SSD):The inner sensor is failed.
(Models：RW46N1DSD):The upper zone sensor is failed.
