CORRECTIVE ACTIONS

NO-FROST Models: Faulty ON/OFF DAMPER

- Check efﬁ ciency of contacts on connector J7 on the PCB;

- Check efﬁ ciency of the damper connection to the connector inside the air duct in the

variable temperature refrigerator compartment;

- Renew ON/OFF damper;

- Renew PCB.

CCZ STATIC models with SECONDARY SOLENOID VALVE fault

- Check efﬁ ciency of contacts on connector J5 on PCB;

- Check impedance on wiring connector J5 pins 1 and 2, ensuring 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 variable temperature compartment is set to OFF.

- Renew solenoid valve;

- Renew PCB. Check

For LED interface PCB:

- Check efﬁ ciency of contacts on connector J13 on PCB;

- Check continuity of connector J13 / LED PCB 5-way and 7-way connectors;

- Renew main PCB;

- Renew display PCB;

For Indesit digit interface PCB and Ariston LED interface PCB on appliances

with CCZ and/or Ever Fresh System:

- Check efﬁ ciency of contacts on connector J13 on PCB;

- Check continuity of connector J13/ interface PCB 4-way connector;

- Renew main PCB;

- Renew display PCB.

For Touch interface PCB:

- Check efﬁ ciency of contacts on connector J13 on PCB;

- Check continuity of connector J13/interface PCB 4-way connector;

- Check continuity of connector J13/connector inside cabinet control panel;

- Check continuity of connector inside cabinet control panel / interface PCB

4-way connector;

- Renew main PCB;

- Renew display PCB.

- Renew PCB.

- Check efﬁ ciency of contacts on connector J2 on PCB;

- Check for impedance on wiring connector J2 pins 3 and 1, ensuring

that the value read is compatible with the value given in the relevant table;

- Check correct connection of the fridge fan inside refrigerator

compartment;

- Renew fridge fan unit;

- Renew main PCB.

- Check efﬁ ciency of contacts on connector J4 on PCB;

- Check impedance on wiring connector J4 pins 1 and 2, ensuring that the value

read is compatible with the value given in the relevant table;

- Renew vacuum pump;

- Renew main PCB.

- Check efﬁ ciency of contacts on connector J2 on PCB;

- Check for impedance on wiring connector J2 pins 4 and 6;

- Renew lamps;

- Renew main PCB.

- Check efﬁ ciency of contacts on connector J11 on the PCB;

- Check NTC probe, ensuring that the impedance value read on pins 3 and 4 of

wiring connector J11 is compatible with the values in the temperature-imped-

ance correlation table (also heat the probe by holding it with your hand where

possible and checking the change in the impedance value);

- Renew main PCB.
