5. NTC-SENSORS FAULT
Abnormal resistance values are interpreted by the electronic as a fault sensor and the display shows a symbol.
If an air sensor is faulty, the compressor will stay on for about 20 minutes and off for 30 minutes.
In case of fault of the sensors:
 Refrigerator (faulty air sensor): the refrigerator display will show symbol
 Refrigerator (faulty evaporator sensor): the refrigerator display will show symbol
(depending on the electronic version)
the refrigerator continues to operate thanks only to the
indications of the air sensor (for more details please refer to
parag. 7.3).
 Freezer (faulty air sensor): the freezer display will show the symbol
At extreme temperatures, alarm levels may be activated even if the sensors are not faulty. The faulty codes for
temperatures higher than + 39°C and lower than - 39°C must not be considered.
