Hello..i have a meat grinder..that have stopped working...i have disassembled it and found out that following parts seems defect....a transient protection NTC...250V maybe 3A..that is marked BS415...and also a Triac ..BT136...in this circuit there is a diode that i don't know what it is... i belive that this circuit is more some kind of overload protection than it's a control circuit !?...the controls are just on-off and reverse...i would much appreciate your help and i don't know if the brand makes a difference but it's a bifinette kh 3460....i think my friends wife who lend it may have just put something too hard for it to grind..so it got to a full stop.....but the glass fuse is o.k. have a nice day...Holger
