FYI, the RUN capacitor only works at STARTUP. At roughly 70% of full rpm " back electromotive force , EMF " stops current flow thru start winding. .
Yes it's got symptoms of a a bad run cap but again what's the amp draw & voltage ?. Could be a bad wire terminal, locked compressor, on and on.

The RUN capacitor is wired in series with the start winding of the motor and stays in the circuit all of the time. They are designed to dissipate heat associated with continuous operation of the motor. The whole purpose of the RUN capacitor is to bring the start winding back in phase with the run winding. The start winding is slightly out of phase with the run winding to provide starting torque for the motor. The RUN capacitor also provides “running torque” once the motor is up and running.
As you can see from the information above, the RUN capacitor is ALWAYS IN THE CIRCUIT helping the compressor / fan / any PERMANENT SPLIT CAPACITOR (PSC) motor perform better.
sayoung before you start correcting people, educate yourself.
