CORRECTIVE ACTIONS
- Check effi ciency of contacts on connector J11 on the PCB;
- Check NTC probe, ensuring that the impedance value read on pins 1 and 2 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.
- Check effi ciency of contacts on connector J11 on the PCB;
- Check NTC probe, ensuring that the impedance value read on pins 5 and 6 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.
