Could a failing Dual Run Capacitor cause the CARRIER COMFORT 15 CENTRAL AIR CONDITIONER to have symptom: Wont Ignite?

The capacitor provides the electrical phase-shift needed to create a rotating magnetic field in the compressor and fan motors. When the internal dielectric fluid or metallized film degrades, the motors cannot generate the starting torque required to spin the rotor. This results in a stalled condition where the motor remains stationary and vibrates at the line frequency, creating the reported humming sound instead of starting the cooling cycle.
