User Manual
Check the fuse: see table in section 4.4.
Replace the electronic control unit.
Check wiring conditions, examining for
loose connections, rust or verdigris. If
wiring needs to be replaced, see the
manual for correct sizing. If wiring is in
good conditions, check battery function
and replace if in poor condition.
Rotate the thermostat to off position. If
the refrigerator continues to function,
then there is continuity on the control
unit. Correct the problem on thermostat
connections (make sure the bridge
is present on C and P and not on C
and T on the electronic control unit).
Rotate the thermostat to off position.
If the compressor switches off but it is
impossible to regulate temperature,
replace the thermostat or recharge the
cooling system.
Check ventilation. The compressor must
be installed in a well-ventilated location.
If possible, remove the refrigerator from
the installation hole. If the refrigerator
operates better, improve ventilation,
consulting the manual for correct
installation. If ventilation is instead
optimal, check for the presence of gas
in the system, contacting a specialised
technician.
