Thanks Klaus,
I replaced the triac just in case (although it tested fine), and I've also replaced C1, which leaked a little when I put 500v across it. Since replacing C1, I have an open circuit. No movement from the motor.
Hi,
This circuit is a 240 volt motor speed controller. There's a missing component (blank space above the triac), which looked like a zener diode, but it melted, so I can't identify it. I've tried diodes, thermistors, and diacs, but the motor only runs at top speed, or not at all. Can anyone...
