thank you for your replies
yes i know the fault description is not really good ^^ but unfortunately i dont know anything else. i got this in a non working condition and all i know is that when switched on it doesnt move at all.
actually i checked the diodes in the diode checking mode and the values i mentioned are the reported voltage drop. so this diode is conducting in both directions. after your suggestion that the surrounding circuitry might effect the test result i desolderd the diode and tested again
and it is indeed conducting in both directions.
again learned something new
i checked the resettable thermal cutoff for continuity and it looks ok.
does anything in the pictures below looks suspicious?

thanks and regards

EDIT: damn.. i checked again and when desolderd the diode is NOT conducting in both directions. so back to square one. anybody an idea what might be wrong?
