longer periods.
42
Possible cause and remedy
Not a fault! To save energy, the compressor runs at a
lower speed when less cooling is required. This
increases the running time of the compressor.
The ventilation gaps in the housing unit have been
covered or become too dusty.
 Do not block the ventilation gaps.
 Clean the ventilation gaps on a regular basis.
The doors have been opened too frequently, or a
large amount of fresh food has been placed inside
and/or frozen at the same time.
 Only open the door when necessary and for as
short a time as possible.
After a while the temperature will return to normal by
itself.
The door is not properly closed.
A thick layer of ice may have formed in the freezer.
 Close the door.
After a while the temperature will return to normal by
itself.
If a thick layer of ice has formed, it will decrease the
cooling performance and increase the energy
consumption.
 Defrost the appliance and clean it.
The room is too warm. The higher the room
temperature, the longer the compressor has to run.

The appliance was not properly installed in the niche.
