Could a failing Dual Run Capacitor cause the RUUD UA14 to have symptom: Loud Buzzing Wont Turn On?

The dual run capacitor provides the essential electrical phase lead required to energized the start windings of the compressor and fan. When the internal dielectric fails, the motor cannot generate the initial torque required to overcome static friction and head pressure, resulting in a Locked Rotor condition. The buzzing sound is the physical manifestation of the 60Hz alternating current passing through the primary windings without resulting in mechanical rotation. Replacing this component restores the necessary torque to initiate the cooling cycle.
