It includes both the \u003cstrong\u003edual run capacitor (P291-4573RS)\u003c\/strong\u003e — which powers both the compressor and condenser fan motor simultaneously — and the \u003cstrong\u003estart capacitor (P281-8806)\u003c\/strong\u003e, which delivers the extra electrical torque needed to kick the compressor into motion on each cooling or heating cycle. When either capacitor fails, you'll typically hear a loud hum with no motor movement, experience a hard shutdown within seconds of startup, or notice the outdoor unit running but not cooling or heating effectively.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs — Dual Run Capacitor (P291-4573RS):\u003c\/strong\u003e 45+7.5 MFD (microfarad) | 370V rated | Round case | Dual-section (compressor + fan) | OEM tolerance ±3% | Superseded by P291-4574RS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs — Start Capacitor (P281-8806):\u003c\/strong\u003e OEM Carrier start capacitor | Factory-matched for PH13NR030000AAAA compressor | Provides high-torque startup boost\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM capacitors are manufactured to Carrier's exact factory tolerance specifications. Generic aftermarket units frequently ship with ±10% MFD variance, which accelerates compressor and fan motor wear 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 touching terminals (use an insulated resistor or discharge tool). Tools needed: 1\/4\" nut driver, needle-nose pliers, multimeter set to capacitance mode. Photograph all wiring connections before disconnecting. Turn off power at both the disconnect box and the thermostat before beginning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
