Sourced to original Carrier specification under part numbers \u003cstrong\u003eP291-5553RS\u003c\/strong\u003e (original) and its current OEM successor \u003cstrong\u003eP291-5554RS\u003c\/strong\u003e, this capacitor stores and releases the precise electrical charge needed to start and sustain both the compressor and condenser fan motor simultaneously. When a dual run capacitor begins to fail, symptoms include a tell-tale hum at startup with no motor spin, hard-starting that trips the breaker, the outdoor fan running while the compressor stays locked out, or the unit short-cycling within minutes of startup on a hot day.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 55+5 MFD (microfarad) | 370V rated (440V-rated successor P291-5554RS is a direct upgrade) | Round case | ±5% factory tolerance | 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM capacitors are manufactured to Carrier's exact tolerance specifications. Generic aftermarket units commonly run ±10% MFD variance, which accelerates motor winding stress, shortens compressor life, and can void equipment warranties.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always discharge the capacitor fully before handling — stored charge can cause serious injury even with power off.

OEM part numbers P291-5553RS and P291-1503 are both factory-discontinued; P291-5554RS (55+5 MFD 440V) and P291-1504 (15 MFD 440V) are the current OEM-authorized successors and direct drop-in replacements. Always verify MFD and voltage ratings against your unit's data plate before ordering.
