Moin ! Ich habe das Problem das der Motor nach dem Tausch nur 5x klackert - er springt danach leider nicht mehr an. Hast du noch eine Idee?

Ich habe Motor + Platine getauscht.

Hallo Ich hab das gleiche Problem, wie habt ihr das gelöst ?

Grüße Andrea

Hallo, habe ebenfalls das "Summen und Klackern " nach dem Einschalten. Gibt es dazu vielleicht eine brauchbare Lösung? Im Elektronikforum beschreiben mehrere User dieses Symptom, wobei eine mögliche Abhilfe ein Austausch eines Eingangsspannungs Kondensator am Netzteil sein könnte?

Original Kommentar:

Vermutung:
Die Spannungsversorgung der Elektronik erfolgt über ein sog. Kondensatornetzteil, das heißt, ein Kondensator ist in Reihe mit der Netzspannung geschaltet und reduziert die Eingangsspannung für die Elektronik. Wenn dieser Kondensator Kapazität verliert, wird auch die Versorgungsspannung für die Elektronik zu niedrig.

Hallo,

habe ebenso das Summen und Klacken (auf Stufe drei gut hörbar). Der Motor scheint anlaufen zu wollen, es macht aber den Eindruck das er klemmt. Gibt es bereits eine Lösung? Vielen Dank euch

Susi -

Moin, und Funktioniert es bei dir wider?

ich habe das gleiche Problem und komme noch nicht weiter.
