Possible cause & Solution
Check that the air outlets are not blocked by food and
ensure food is placed within the appliance to allow
sufficient ventilation.
Ensure the door can be fully closed . To remove the frost,
please refer to the cleaning and care chapter.
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.
Increase the temperature by following the "Display controls"
chapter.
Check whether the top of the refrigerator is tilted back by
0.4"-0.6"（10-15mm） to allow the doors to self close, or if
something inside is preventing the doors from closing.
This is normal. The bubbling comes from the refrigerant
coolant liquid circulating through the refrigerator.
The LED light may be damaged. Refer to replace LED
lights in cleaning and care chapter.
The control system has disabled the lights due to the
door being kept open too long, close and reopen the
door to reactivate the lights.
