FAULT CORRECTIVE ACTIONSCAUSE
- Check for water leaks that may affect connector J1 causing the relative contacts to
short;
- Check motor terminal board (possible problems due to incorrect connection which may
cause short-circuits);
- Renew motor;
- Renew PCB.
- Check effi ciency of contacts on connector J1 on the PCB;
- Check on wiring connector J1 between pins 3 and 2 for an impedance value that is
compatible with the value given in the specifi c table.
- Check that the compressor is not stopped due to overtemperature conditions (thermal
cutout open)
- Renew motor;
- Renew PCB.
- Renew PCB.
- Check effi ciency of contacts on connector J6 on the PCB;
- Check impedance on wiring connector J6 between pins 2 and 1 checking that the value
is compatible with the value given in the relevant table;
- Check correct connection of the freezer fan on the freezer compartment wiring junction
box;
- Renew freezer fan unit;
- Renew PCB.
- Check effi ciency of J3 connector contacts
on PCB;
- Check effi ciency of connection of electronic damper at foam protected connector
behind multifl ow;
- Renew electronic damper;
- Renew PCB.
- Check effi ciency of contacts on connector J6 on the PCB;
- Check condition by checking for impedance on wiring connector J6 pins 3 and 4;
- Check connections of the defrost heating elements and possible short circuits on the
freezer compartment wiring junction box;
- Renew heating element.
- Renew PCB
- Check effi ciency of contacts on connector J6 on the PCB;
- Check for continuity of the defrost heating element on pins 3 and 4 of connector J6,
ensuring that the impedance value read is compatible with the value given in the relevant
table;
- Check for correct connection of the defrost heating element and the drip tray heating
element on the freezer compartment wiring junction box;
- Check the correct impedance value on the defrost heating element across the heating
element terminals;
- Check that the fuses have not blown;
- Renew defrost heating element;
- Renew PCB.
- Check
effi ciency of contacts on connector J8 on the PCB;
- Check for impedance on wiring connector J8 pins 1 and 2 and ensure that the value
is compatible with the value given in the relevant table;
- Check correct switching of the solenoid valve With the compressor running, check that
the solenoid valve switches when the refrigerator compartment is set to OFF.
- Renew solenoid valve;
- Renew PCB.
- In the case of a production PCB, renew PCB and EEPROM;
- In the case of replacement PCB and EEPROM, check correct insertion of EEPROM in
PCB socket.
