Problem
The compressor runs
continuously.
The compressor is
switching on more
frequently and for
longer periods.
The compressor is
switching on more
frequently and for
longer periods of time,
so the temperature in
the appliance is
dropping.
Cause and remedy
This is not a fault. To save energy, the compressor
runs at a lower speed, but for longer, when less
cooling is required.
The ventilation gaps in the housing unit have been
covered or become too dusty.
 Do not block the ventilation gaps.
 Dust the ventilation gaps regularly.
The door has 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.
The required temperature will re-establish itself after a
while.
The door is not properly closed.
A thick layer of ice may have formed in the freezer.
 Close the door.
The required temperature will re-establish itself after a
while.
If a thick layer of ice has formed, it will reduce
efficiency and increase the energy consumption.
 Defrost the appliance and clean it.
The ambient temperature is too high. The higher the
room temperature, the longer the compressor will run
for.
 See "Installation - Location".
The appliance was not properly installed in the niche.
 See "Installation - Building in the appliance".
The temperature setting is too low.
 Adjust the temperature.
The Super freeze function is still switched on.
 You can switch off the Super freeze function earlier
to save energy.
