Miele FN 35402 i Operating And Installation Instructions page 45

The compressor runs more frequently and for longer periods of time,
the temperature in the appliance drops.
Problem
The compressor is
switching on more
frequently and for
longer periods.
Cause
The ventilation gaps in the
housing unit have been
covered or become too
dusty.
The door has been opened
too frequently, or a large
amount of food has been
put in at once.
The door is not properly
closed.
A thick layer of ice may
have formed in the freezer.
The ambient temperature is
too high. The higher the
room temperature, the
longer the compressor will
run for.
The appliance was not
properly installed in the
niche.
