●Has the "Quick Freezing" mode been activated? (P.12)
●Is the temperature setting of the freezer compartment and
fridge compartment set to something other than "Med"?
●Has the door been opened frequently or has hot food been
placed in the refrigerator?
●The learning function may automatically disable ECONAVI
operation during times of frequent use.
●Is there a power failure?
If a power failure occurs, the learning function data collected
up until the point of power failure will be lost.
The ECONAVI operation will rarely be performed until the
learning function has collected data again.
●If the auto defrost function is turned on during ECONAVI
operation, the normal cooling operation will need to be
performed after defrost.
Therefore the ECONAVI operation may be stopped during
this defrost/cooling process.
●The learning function may sometimes restart the normal
cooling operation.
●Is the light intensity sensor hidden?
●Are there dirt or scratches on the control panel where the light
intensity sensor is located?
●ECONAVI operation may be performed while the refrigerator
is being used depending on the conditions of use, but the
cooling performance is maintained.
