Ice and f rost form on t he surface of evaporator during
operation. A thick layer of ice or frost a cts as heat
insulation and hinders thermal conduction.
Defrost t he freezer c ompartment in the shortest time
possible to avoid thawing of frozen foods.
Do not remove the ice or
compartment wi th a shar p or pointed i tem. Other wise
the evaporator surface may get damaged.
Wipe off defrost water from time to time with sponge.
Place a container of hot water (do not use boiling water)
near the door of freezer compartment to speed up the
defrosting process.
Dry the freezer compartment and place the frozen food
back.
Reconnect the refrigerator after defrosting.
Start up t he r efrigerator by adj usting th e t emperature
control knob.
Close the door of freezer compartment.

12. Problem Diagnosis

The latest manufacture t echniques and state-of-the-art
refrigeration and freezing technology are adopted to
ensure safe and reliable oper ation o f y our appliance. In
doubt of fault, make sure to check first as described below
before making a service call:
Things to be noted:
The compressor (also known as refrigerating unit) doesn't
operate all the time without stop.
The compressor is controlled by
temperature regulator represented by a temperature dial.
When the interior temperature ex ceeds the pre set
temperature, the compressor st arts automatically and
when the interior temperature falls below the present
temperature, the compressor stops automatically.
It's normal that compressor makes noise during operation.
The noise comes from th e m otor. The flow o f r efrigerant
through the refrigerating system may make a gurgling
noise. These noises don't mean a fault of the refrigerator.
The ex terior surface may be wet when i t's cold and the
ambient tem perature i s low. I t's normal and the exterior
surface will become dry as the ambient temperature rises.
If the reasons of such phenomena can't be i dentified and
solved, please consult the service center.

13. Troubleshooting

a) Problem: R efrigerator does not oper ate ( does not
work)
Please check:
Is the power cord in good condition? Is the refrigerator
properly plugged in the outlet?
Is there a power interruption? (Use a small appliance to
check out, e.g. agitator or hair dryer)
frost in the freezer
the automatic
Is t he refrigerator started up?
Is the fuse broken? Or in poor contact?
b) Problem: The inner compartment is not cool
enough; the compressor cycles on and off
frequently;
Please check:
The freezer compartment should stand still
for at least 2 hours after i nstallation to st abilize the
refrigerant circulation system. If it
doesn't work, un plug the refrigerator and tilt the
refrigerator to one side for a while or place it on an
inclined plane and then place it to the original position.
Connect the refrigerator after 2 hours. Keep the door(s)
closed for 12 hours.
Is the door properly closed? If so, the door gasket
should press on the external cabinet securely and
evenly.
Test: It should be difficult to pull out a piece of paper
caught up between the door gasket and the external
cabinet.
If the paper slips away easily, consult the service
center.
If the re is thick ice in the freezer compartment. (See
"Cleaning and Maintenance")
Is the refrigerator exposed to direct sunshine or near a
heat source (oven, radiator, etc.)?
What to do: Do not expose the refrigerator to direct
sunshine; keep the refrigerator away from any heat
source; install
refrigerator and the heat source (see "Location").
Is the inner compartment overloaded?
Is the room well ventilated? Is the air vent obstructed?
Is the heat exchanger (co ndenser) on the back
covered by dust?
c) The te mperature of refrigerator com partment is
too low
Please check:
Is the temperature regulator properly set?
Is the door of freezer compartment properly closed?
Is there a lot of fresh food (more th an 1 kg) in the
freezer compartment? (If t he freezer com partment
operates for long p eriods, the temperature of
refrigerator compartment falls accordingly.)
d) T he f reezer compartment i s t oo warm and f rozen
foods are thawed
Is the am bient temperature too low? ( If so, the
refrigerating unit will malfunction, r esulting in higher
temperatures in the freezer compartment.)
What to do: Raise the ambient temperature.
