Possible cause
There is no voltage
present in the DC power
socket in your vehicle.
Defective compressor.
Voltage of the vehicle
battery is too low.
The DC power socket is
dirty. This results in a
poor electrical contact.
The fuse of the DC plug
has blown.
The vehicle fuse has
blown.
The cooling device has
switched off due to an
internal fault.
Suggested remedy
The ignition must be switched on in most
vehicles to apply current to the DC power
socket.
This can only be repaired by an
authorized customer services unit.
Test the vehicle battery and charge it as
needed.
If the plug of your cooling device
becomes very warm in the DC power
socket, either the DC power socket must
be cleaned or the plug has not been
assembled correctly.
Replace the fuse (8 A) in the DC plug, see
chapter "Replacing the fuse" on page 17.
Replace the vehicle's DC power socket
fuse (usually 15 A). Please refer to your
vehicle's operating manual.
This can only be repaired by an
authorized repair center.
