Merci beaucoup pour ce tutoriel.

Je ne sais pas réellement ce qui a bloqué le ventilateur, je l'ai tourné plusieurs fois à la main et d'un coup il a fonctionné de nouveau. Merci encore

Avec grand plaisir ! :)

Parfois les hélices sont bloquées par un micro organisme.

Et bien la pouasse! 😟 Merci pour le tuto démontage / test mais je relance le ventilo tout est ok j’allume impec mais ça s’éteint automatiquement après 3/4 secondes , donc ce ne serait pas le problème…

Lumière verte clignotante, puis parfois plus du tout , on sent une envie d’y aller mais obligé d’insister sur l’allumage avant que ça ne parte … je crains que ce ne soit plus sérieux 😟

Merci de votre aide .

Merci beaucoup, la garantie de mon appareil finissait en juin et panne début septembre.

J'ai suivi à la lettre votre tuto et c bon.

Même si je n'ai rien trouvé, sans doute qlq chose de minuscule.

A noter qu'il faut un tournevis étoilé de toute petite taille que je n'avais pas.

Mais je peux à nouveau profiter de l'appareil.
