POSSIBLE CAUSES
The appliance door is opened too
often.
Air circulation around the unit is
obstructed.
Unit is switched off or is not
supplied with power.
Temperature controller is set to
"OFF".
Ambient temperature is too low.
Door not closed tightly or door
seal is not fully open.
The condenser releases warm air
into the environment. If the
ambient temperature is too high,
heat can build up. As soon as the
ambient temperature has
dropped, the unit cools normally
again. It is essential to observe
the distances (see chapter Gerät
aufstellen).
CAUSE / REMEDY
Caused by the compressor when it is in
operation.
Arises from the circulation of the
refrigerant in the unit.
The temperature controller switches the
compressor on or off.
Check if the condenser at the back of the
unit is loose.
Fasten the condenser.
MEASURES
Do not open the appliance
door unnecessarily.
Leave the area around the unit
free.
Check the power supply and
fuses. Check that the mains
plug is correctly inserted in the
socket.
Check whether there is voltage
at the socket.
Check the temperature
controller settings.
