Hi
 As I think Joe mentioned, the electrolytic capacitors are usually
used as motor run capacitors and not starting. These are non-polarized.
Starting capacitors are usually oil/paper ( newer don't have PCB's ).
This is because the starting capacitors require more current that
would blow up a run capacitor. Run capacitors are used to help
maintain efficiency of the motor while running. They help to
keep a rotating field and help to pull the inductive load back
to a resistive load from the AC side.
