Fault description
The temperature fails to
reach the desired set-
point.
Poor cooling perform-
ance. The desired set-
point cannot be reached
even though the cooling
unit is in operation.
29.11.2024
Cause
Error during temperature measure-
ment.
Fans are defective, air circulation in
the incubation chamber is therefore
insufficient.
The door is not closed completely.
The room temperature is too high.
IMPORTANT: The room tempera-
ture refers to the temperature
directly on the device. This can be
significantly higher than the tem-
perature in other parts of the room.
Other devices with strong heat radi-
ation are located in the immediate
vicinity of the device (e.g. ultra-low
freezers or refrigerated centrifuges).
A barrier in the room prevents cir-
culation of cold air.
The room temperature is not con-
stant (e.g. because the air condi-
tioning is turned down on the
weekend).
Required minimum distances for
air circulation are not observed.
The device has been pushed back
against the wall.
