Problem
The compressor comes
on less and less often
and for shorter periods
of time. The
temperature in the
appliance rises.
An LED indicator light is
flashing at the back of
the appliance at the
bottom near the
compressor (depending
on model).

Cause and remedy
This is not a fault. The set temperature is too high.
 Adjust the temperature.
 Check the temperature again after 24 hours.
The food begins to defrost.
The room temperature is lower than the ambient
temperature for which the appliance is designed.
Operating in a room which is too cold will cause the
compressor to switch off for too long, causing the
freezer to become too warm.
 See "Installation - Location".
 Increase the temperature of the room.
This is not a fault. The electronic unit for the
compressor is equipped with an operation and fault
diagnosis LED indicator light which flashes every 15
seconds (depending on model).
