TROUBLESHOOTING
1-IF YOUR REFRIGERATOR DOES NOT WORK
Check that:
−
the thermostat is not set to "STOP"
−
the electrical system circuit breaker on the appliance has not tripped.
−
the fuse in the electronic control unit has not blown
−
the power supply cable is not faulty
−
the battery is delivering sufficient power
−
the voltage on the electronic control unit terminal board corresponds to that of the
battery.
If there is a voltage drop of over 0.2-0.4 V check that:
−
the size of the cable connecting the battery to the electronic control unit corresponds to
specifications (see table in the Danfoss instructions enclosed)
−
any junction points in the power line are efficient and terminals are properly tightened.
−
there are no signs of oxidisation on the battery poles and contact points
2-EXCESS REFRIGERATOR NOISE
Check that:
−
the refrigerator and refrigerating unit are positioned on flat surfaces
−
the refrigerator is not touching other objects that may cause vibrations
−
the refrigerating circuit tubes at the back of the unit are not touching or vibrating against the
appliance
3-INSUFFICIENT REFRIGERATING POWER
Check that:
−
the door is sealed properly
−
the refrigerator is not positioned close to heat sources
−
the refrigerator and remote refrigerating unit are sufficiently ventilated
−
frost has not accumulated on the evaporator
−
dust has not blocked the condenser
−
the fan rotates freely (in forced cooling models)
−
the refrigerator is not over-full
If, after checking the above, the refrigerator still does not function, consult your
nearest assistance centre.
