Hello,
I am trying to repair an old Kenwood chef 250. The motor makes a noise and stops immediately. I'd like to check its triac or thyristor but I can't find the 71719 datasheet.
Can anyone help me?
Thanks
Bernard

Welcome to ETO

and the first reply given therein indicating it a a LDO regulator.

With the power off, check that the drive shaft is free to rotate. This could be a bearing seizing up.
Almost any 8A 600V (or greater spec) triac should be ok as a replacement.

in the reference i indicated, bigal_scorpio had replaced the same with BT136 that worked well.
but he had also cleeaned the commutator brushes. see link here.
