2.6 Energy saving tips

The appliance should be located in the coolest area of the room, away from heat-producing appliances or heating ducts, and out of direct sunlight.
Let hot foods cool to room temperature before placing them in the appliance. Overloading the appliance forces the compressor to run longer. Foods that freeze too slowly may lose quality or spoil.
Be sure to wrap foods properly, and wipe containers dry before placing them in the appliance. This cuts down on frost build-up inside the appliance.
The appliance storage bin should not be lined with aluminum foil, wax paper, or paper towels. Liners interfere with cold air circulation, making the appliance less efficient.
Organize and label food to reduce door openings and extended searches. Remove as many items as needed at one time, and close the door as soon as possible.

Troubleshooting

You may try to solve the following simple problems by yourself. If they cannot be solved, please contact the after-sales department.

Failed operation| Check whether the appliance is connected to power or whether the plug is in well contact.
Check whether the voltage is too low.
Check whether there is a power failure or partial circuits have tripped.
---|---
Odor| Odorous foods shall be tightly wrapped.
Check whether there is any rotten food.
Clean the inside of the refrigerator.
Long-time operation of the compressor| The long operation of the refrigerator is normal in summer when the ambient temperature is high.
It is not recommended to have too much food in the appliance at the same time.
Food shall get cool before being put into the appliance.
The doors are opened too frequently.
Light fails to get lit| Check whether the refrigerator is connected to the power supply and whether the illuminating light is damaged.
Doors cannot be properly closed| The door is stuck by food packages.
The refrigerator is tilted.
Loud noise| Check whether the floor is level and whether the refrigerator is placed stably.
Check whether accessories are placed at proper locations.
The door seal fails to be tight| Remove foreign matters on the door seal.
Heat the door seal and then cool it for restoration (or blow it with an electrical drier or use a hot towel for heating).
Water pan overflows| There is too much food in the chamber or food stored contains too much water, resulting in heavy defrosting.
The doors are not closed properly, resulting in frosting due to the entry of air and increased water due to defrosting.
Hot housing| Heat dissipation of the built-in condenser via the housing is normal.
When housing becomes hot due to high ambient temperature and storage of too much food, it is recommended to provide sound ventilation to facilitate heat dissipation.
Surface condensation| Condensation on the exterior surface and door seals of the refrigerator is normal when the ambient humidity is too high. Just wipe the condensate with a clean towel.
Abnormal noise| Buzz: The compressor may produce buzzes during operation, and the buzzes are loud, particularly upon start or stop. This is normal.
Creak: Refrigerant flowing inside of the appliance may produce a creak, which is normal.
