The correct temperature
This loss of coldness is no cause for
concern in the following circumstances:
– when the door has been left open for
a while, e.g. for removing or storing a
large amount of food,
– when fresh food is being frozen.
However, if the temperature in the
freezer section remains above
-18 °C for a long time, check that the
frozen food has not started to
defrost. If it has, check that the food
is safe to use and if it is, then use it
as soon as possible.
