The dual run capacitor delivers and sustains the electrical charge required to start and run both the compressor and the condenser fan motor simultaneously. A failing capacitor is one of the most common causes of warm air from a working system — symptoms include a loud humming or buzzing with no motor start, a fan that only spins when manually pushed, a compressor that short-cycles within minutes, or a unit that draws high amperage and trips the breaker. Replacing it promptly prevents cascading damage to the compressor and fan motor. This listing also includes the associated single run capacitors \u003cstrong\u003eP291-0403\u003c\/strong\u003e and \u003cstrong\u003eP291-1503\u003c\/strong\u003e as companion parts for a complete capacitor service on this platform.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 45+5 MFD (microfarad) | 370 VAC rated | Oval case | 50\/60 Hz | ±5% factory tolerance | Aluminum construction | UL approved current interrupter | Non-PCB dielectric fluid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM capacitor is manufactured to Carrier's exact tolerance specification.
