The dual run capacitor stores and delivers the electrical charge that keeps both the compressor and condenser fan motor running continuously. The start capacitor provides the extra torque burst needed to kick the compressor into motion on each cycle. When either fails, symptoms include a humming unit with no compressor start, a fan that spins slowly or not at all, or a system that trips off within seconds of startup.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Run Capacitor Specs (P291-4573RS):\u003c\/strong\u003e 45+7.5 MFD (microfarad) | 370V rated | Round case | Superseded by P291-4574RS — this listing ships the current OEM equivalent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStart Capacitor Specs (P281-8806):\u003c\/strong\u003e 88–108 MFD | 330V rated | Includes integrated bleed resistor | 2.06\" diameter round case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM capacitors are factory-tolerance matched (±5% MFD).
