Rated at \u003cstrong\u003e4 MFD (microfarad) at 370 VAC\u003c\/strong\u003e, this oval-style run capacitor remains energized throughout the entire operating cycle of your fan motor or compressor — providing the phase-shifted current needed for smooth, efficient motor operation. When a run capacitor fails, you'll typically notice the unit humming without starting, a fan motor that spins weakly or only with a manual push, or a system that short-cycles and shuts off shortly after startup. This genuine Carrier \/ Totaline part (P291-0403) is the correct factory replacement and also cross-references to alternate OEM part numbers P291-1003 and P291-1503.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 4 MFD (µF) | 370 VAC | Oval case | 50\/60 Hz | Replaces OEM P\/N 97F5704, HC90AA004, HC91CA004, HC90AB004\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM capacitor is built to ±5% MFD tolerance and tested to 60,000 service hours with 100% electrical testing at the factory. Generic alternatives often run ±10% tolerance, which accelerates motor winding wear and increases compressor start stress over time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 1\/5\u003c\/strong\u003e — Disconnect power at the disconnect box and allow 5 minutes for the capacitor to self-discharge before touching terminals. Tools needed: flathead or Phillips screwdriver, needle-nose pliers, optional multimeter to verify discharge.
