The run capacitor provides a continuous phase-shifted current to keep the condenser fan motor or blower motor running at full torque and efficiency. When this capacitor fails, you'll typically notice the motor humming but failing to spin, intermittent shutdowns, reduced airflow, or the unit tripping on high-pressure lockout due to an overworked compressor. Left unaddressed, a weak or failed run capacitor can cause permanent motor winding damage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 4 MFD (microfarad) | 370 VAC rated | Oval case | Single (non-dual) run capacitor | Carrier OEM part number P291-0403 | Cross-references: HC90AA004, HC91CA004, HC90AB004, 97F5704, C304L, 27L571\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM-spec capacitor is manufactured to exact Carrier factory tolerances (±5% MFD). Generic aftermarket units often carry ±10% tolerance, which accelerates motor bearing wear over time and can shorten equipment service life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Discharge the capacitor fully before handling any terminals. Tools needed: 1\/4\" nut driver, needle-nose pliers, multimeter (capacitance setting). Always photograph existing wiring connections before disconnecting. Turn off all power at disconnect box before beginning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty against defects.
