1. Warning and precautions for safety
Please observe the following safety precautions in order to use
safely and correctly the refrigerator and to prevent accident and
danger during repair.
1. Be care of an electric shock. Disconnect power cord from wall
outlet and wait for more than three minutes before replacing PCB
parts. Shut off the power whenever replacing and repairing electric
components.
2. When connecting power cord, please wait for more than five
minutes after power cord was disconnected from the wall outlet.
3. Please check if the power plug is pressed down by the
refrigerator against the wall. If the power plug was damaged, it may
cause fire or electric shock.
4. If the wall outlet is over loaded, it may cause fire. Please use its
own individual electrical outlet for the refrigerator.
5. Please make sure the outlet is properly earthed, particularly in
wet or damp area.
6. Use standard electrical components when replacing them.
7. Make sure the hook is correctly engaged. Remove dust and
foreign materials from the housing and connecting parts.
8. Do not fray, damage, machine, heavily bend, pull out or twist the
power cord.
9. Please check the evidence of moisture intrusion in the electrical
components. Replace the parts or mask it with insulation tapes if
moisture intrusion was confirmed.
10. Do not touch the ice maker with hands or tools to confirm the
operation of geared motor.
11. Do not let the customers repair, disassemble and reconstruct
the refrigerator for themselves. It may cause accident, electric
shock, or fire.
12. Do not store flammable materials such as ether, benzene,
alcohol, chemicals, gas, or medicine in the refrigerator.
13. Do not put flower vase, cup, cosmetics, chemicals, etc., or
container with full of water on the top of the refrigerator.
14. Do not put glass bottles with full of water into the freezer. The
contents shall freeze and break the glass bottles.
15. When you scrap the refrigerator, please disconnect the door
gasket first and scrap it.

5.Trouble shooting
5.1 Common problem and checking
If you experience a problem with your appliance or are concerned that the appliance is not
functioning correctly, you can carry out some easy checks before calling for service,
please see below.
Warning! Don’t try to repair the appliance yourself. If the problem persists after you have
made the checks mentioned below, contact a qualified electrician, authorized service
engineer or the shop where you purchased the product.
Problem
Possible cause & Solution
Appliance is not working
correctly
Check whether the power cord is plugged into the power outlet
properly.
Check the fuse or circuit of your power supply, replace if
necessary.
It is normal that the freezer is not operating during the defrost
cycle, or for a short time after the appliance is switched on to
protect the compressor.
Odours from the
compartments
The interior may need to be cleaned
Some food, containers or wrapping cause odours.
Noise from the appliance
The sounds below are quite normal:
Compressor running noises.
Air movement noise from the small fan motor in the freezer
compartment or other compartments.
Gurgling sound similar to water boiling.
Popping noise during automatic defrosting.
Clicking noise before the compressor starts.
Other unusual noises are due to the reasons below and may
need you to check and take action:
The cabinet is not level.
The back of appliance touches the wall.
Bottles or containers fallen or rolling.
A layer of frost occurs in
the compartment
Check that the air outlets are not blocked by food and ensure
food is placed within the appliance to allow sufficient ventilation.
Ensure that door is fully closed. To remove the frost, please
refer to the“Cleaning and care” chapter.
Temperature inside is
too warm
You may have left the doors open too long or too frequently; or
the doors are kept open by some obstacle; or the appliance is
located with insufficient clearance at the sides, back and top
