    - pendant le fonctionnement conforme à l'emploi de l'appareil frigorifique (1) à usage domestique, fonctionnement du ventilateur (22) avec vitesse régulée conformément à une vitesse théorique du ventilateur (22), prédéfinie au moins indirectement, et
    - pendant un mode de vérification, fonctionnement non régulé du ventilateur (22), détermination de la vitesse réelle du ventilateur (22) et évaluation de la vitesse réelle au moyen d'un dispositif de commande électronique (9) de l'appareil frigorifique (1) à usage domestique afin d'identifier un état de fonctionnement anormal du ventilateur (22),
    dans lequel l'appareil frigorifique (1) à usage domestique comprend un onduleur (31) ménagé pour commander le ventilateur (22), doté de modulation de largeur d'impulsion, lequel onduleur, pendant le mode de vérification, fonctionne avec un rapport cyclique prédéterminé associé au mode de vérification,
    dans lequel l'appareil frigorifique (1) à usage domestique comprend un régulateur (32) ménagé pour la commande de l'onduleur (31) et pour le fonctionnement du ventilateur (22) avec vitesse régulée, lequel régulateur est commandé par le dispositif de commande (9) électronique,
    et dans lequel, en raison du fait que le rapport cyclique prédéterminé associé au mode de vérification est attribué au régulateur (32) par le dispositif de commande (9) électronique, la régulation de vitesse du ventilateur (22) réalisable par le régulateur (32) est désactivée afin que le ventilateur (22) soit commandé de manière non régulée par l'onduleur (31) pendant le mode de vérification.
  2. Procédé selon la revendication 1, présentant l'évaluation de la vitesse réelle (nist) par comparaison de la vitesse réelle (nist) avec une vitesse escomptée du ventilateur (22) pour un état de fonctionnement normal du ventilateur (22).
  3. Procédé selon l'une quelconque des revendications 1 à 2, présentant le fonctionnement du ventilateur (22) en mode de vérification pour une durée (Tv) prédéterminée directement après un démarrage du ventilateur (22) à partir de l'arrêt, et fonctionnement du ventilateur (22) avec vitesse régulée après la fin de la durée (Tv) prédéterminée.
  4. Procédé selon la revendication 3, présentant le démarrage du ventilateur (22) à partir de l'arrêt pendant une phase de démarrage du ventilateur (22), précédant directement le mode de vérification, à partir de l'arrêt du ventilateur (22).
  5. Procédé selon l'une quelconque des revendications 1 à 4, dans lequel l'appareil frigorifique (1) à usage domestique comprend un système de canaux (21) dans lequel sont disposés un évaporateur (20) du circuit de refroidissement (5) et le ventilateur (22), et lequel est couplé à l'espace intérieur (4) pouvant être refroidi, dans lequel le ventilateur (22) disposé dans le système de canaux (21) est configuré pour transporter l'air refroidi au moyen de l'évaporateur (20) dans l'espace intérieur (4) pouvant être refroidi, et dans lequel l'état de fonctionnement anormal du ventilateur (22) représente un givrage de l'évaporateur (20).
  6. Procédé selon la revendication 5, présentant l'évaluation de la vitesse réelle (nist) par comparaison de la vitesse réelle (nist) avec une vitesse escomptée du ventilateur (22) pour un évaporateur (20) non givré, et/ou le lancement d'un dégivrage de l'évaporateur (20) en raison de la vitesse réelle (nist) évaluée du ventilateur (22) pendant le mode de vérification, notamment lorsque la vitesse réelle (nist) dépasse une valeur seuil prédéfinie pendant le mode de vérification.
  7. Procédé selon l'une quelconque des revendications 1 à 6, dans lequel le circuit de refroidissement (5) présente un compresseur (60) et un condenseur (62), et dans lequel le ventilateur (22) est ménagé pour transporter l'air échauffé par le condenseur (62) dans les environs de l'appareil frigorifique (1) à usage domestique, et dans lequel l'état de fonctionnement anormal représente un encrassement du condenseur (62) et/ou une défaillance du ventilateur (22), présentant
    - identification d'un encrassement du condenseur (62) et/ou identification d'une défaillance du ventilateur (22) en raison de l'évaluation de la vitesse réelle du ventilateur (22) pendant le mode de vérification, et
    - fonctionnement du compresseur (60) dans un mode de fonctionnement plus en douceur en raison de l'encrassement identifié du condenseur (62) et/ou de la défaillance du ventilateur (22).
  8. Appareil frigorifique à usage domestique présentant un corps (2) calorifugé doté d'un réservoir intérieur (3) qui délimite un espace intérieur (4) pouvant être refroidi, ménagé pour stocker des aliments, un circuit de refroidissement (5) destiné à refroidir l'espace intérieur (4) pouvant être refroidi, et au moins un ventilateur (22), caractérisé en ce que l'appareil frigorifique (1) à usage domestique est configuré pour réaliser le procédé selon l'une quelconque des revendications 1 à 7.
