The dual run capacitor stores and releases the electrical charge that keeps both the compressor and condenser fan motor running during normal operation, while the start capacitor delivers the high-torque burst of current needed to get the compressor spinning on each cooling or heating cycle. When either fails, you'll typically experience symptoms such as a humming compressor that won't start, a system that trips the breaker immediately, or a unit that short-cycles within the first few minutes of operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Run Capacitor Specs (P291-2553RS):\u003c\/strong\u003e 25+5 MFD (microfarad) | 370 VAC rated | Round case | Replaces HC98JA026, HC98CA026, P291-2553R | Factory-matched ±3% tolerance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStart Capacitor Specs (P281-1896S):\u003c\/strong\u003e 189–227 MFD | 330 VAC rated | Round case | 50\/60 Hz | Replaces 092A189B330CE7X, P2811896S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM Carrier capacitors are manufactured to exact factory tolerances, ensuring precise MFD ratings and voltage stability.
