Hi,
There a motor with variable speed control ruled by u211b2 (originally u211b, though I think there's no difference). There was a problem with TRIAC (lack of lead) that we handled successfully but then something happened and it stopped working.
I check all resistors, capacitors and a couple of varistors, all seem fine. TRIAC is ok. At first sight everything is ok but still it doesn't work. The scheme attached is almost 100% correct (a very common one).
Thanks in advance!!!
