The compressor, managed by the electronic board, is normally on when at least one of the two compartments demands refrigeration, i.e., when the temperatures of the freezer and/or refrigerator air sensor are such as to activate at least one refrigeration demand. When both compartments no longer need refrigeration, the refrigeration demands are deactivated and the compressor is switched off. There are particular situations when, despite demands for refrigeration by the appliance's compartments, the compressor remains switched off.
Compressor protection: in particular the compressor switches on 8 minutes after it has been switched off. This allows the gas pressures inside the thermodynamic circuit to equalize without risk of the compressor becoming blocked due to too high pressures inside the thermodynamic circuit. - Long periods of activity: if the compressor remains on for more than 4 hours it is switched off, even if the compartments demand refrigeration. - Pause after defrost: at the end of every defrost, the compressor observes 10 minutes of protection so that the water formed can completely run off before the evaporator starts to cool again.
