Motorul e functional dar are o placuta electronica care cred ca e variator de tensiune. Pe aceasta e un triac BTA16/600B si as dori sa imi spuneti cum se masoara triacul cu multimetrul pentru a il inlocui. Eu am 4 triace bune. Va rog sa ma ajutati.Multumesc anticipat!

schema este testata de mine cu ceva timp in urma.

alimentati montajul(becul este stins) iar cand apasati scurt pe buton(nu este intrerupator) triacul primeste impuls in poarta si astfel becul incepe sa lumineze si ramane aprins pana se opreste alimentarea montajului.

la unele aspiratoare exista si un termistor pe montaj care intrerupe alimentarea motorului cand acesta se incinge.

dupa cateva ore de ohihna se constata ca aspiratorul porneste si functioneaza normal.

daca montajul este defect atunci nu este greu de depanat,de regula se defecteaza triacul dar trebuie totusi verificat piesa cu piesa.
