You can't use the ones with the stripe, there is no "positive" for an AC motor. You MUST use non-polarized caps, those will have no stripe. Also, you don't want to put too much capacitance from the brushes to ground, get the right caps.
Not even close, the part you removed was a triac, and this is a MOSFET!

@gunrunnerjohn would 10uf NP caps be too much? What would be the symptoms off "too much?"

You can't use the ones with the stripe, there is no "positive" for an AC motor. You MUST use non-polarized caps, those will have no stripe. Also, you don't want to put too much capacitance from the brushes to ground, get the right caps.
