I didn't have one intended for the purpose so I used a pair of Angela MKP caps (correct capacitance, higher voltage) I had left over from tube amp building days. Dryers run without these if you give ...

As an electric motor’s rotor turns in close proximity to the motor windings, a bucking voltage or back electromotive force (EMF) is generated. The back EMF (BEMF) generated across the start winding is ...
