What type of Triac is used on the 8200? I’ve burnt mine out and can’t read the number.

I have had the same trouble with control board burned out. I bought the rotary tool 2 months ago, in France and live in Brazil. So, sending the machine to US (and have it back) I believe will be so much expensive. I already have the P/N of the board and will try to buy it frm some Dremel service. Hope it works.

My Dremel 8200 always works full, without speed control, and perhaps the same fault as yours. If you want I pass photos of the interior .. Actualización (03/10/19) I have looked at it. It is a Mosfet channel n. The model is 80NF03L-04. If you want I pass photos, since I have reviewed my dremel and it is what has burned to me.
