/diy/ - Do It Yourself

Hmm shit. So what else is likely to be fucked?
It's an electronic sewing machine pedal -- something similar to pic related.

There's a voltage regulator (one you can modify with a small plastic screw -- possibly to adjust the minimum or maximum speed?), a triode, a transformer these four capacitors and a couple of resistors.
The TRIAC controls the voltage the motor gets and it's controlled by a sliding component that is actuated by the pedal pressing down and moving the moving part front/back.

The sliding component's feet had come lose so I resoldered these. Unfortunately it still didn't work. However with some wiggling, the motor spun up for a second sometimes. I can't reliably reproduce that though and all the contacts seem fine on the rest of the board. I reflowed them regardless.

So, given that the motor did spin up for a moment, can the TRIAC even be the problem?
Anyway, I can't seem to find this sliding component (I have no idea what it's called) so I'm inclined to order another TRIAC.

I do have another sewing machine pedal I could solder to this proprietary connector, but I'd like to fix this one if only for the experience/learning effect.
