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 the direct sunlight.
Let hot foods cool to room temperature before placing 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.
Appliance storage bin should not be lined with aluminum foil, wax paper, or paper toweling. 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 them 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| Long operation of the refrigerator is normal in summer when the ambient temperature is high
It is not recommended having 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 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
Door seal fails to be
tight| 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 entry of air and
increased water due to defrosting
Hot housing| Heat dissipation of the built-in condenser via the housing, which 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| 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 creak, which is normal.
