The dual run capacitor stores and releases the electrical charge needed to start and sustain both the compressor and the condenser fan motor simultaneously. When it fails, you'll hear a telltale hum with no motor movement, notice the system short-cycling, or find the outdoor unit completely unresponsive — all classic signs of capacitor failure. A companion \u003cstrong\u003estart capacitor (P281-8806, 88–108 MFD \/ 330V)\u003c\/strong\u003e is also available and recommended for inspection any time the dual run cap is replaced.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Run Capacitor Specs (P291-5073RS):\u003c\/strong\u003e 50+7.5 MFD (microfarad) | 370V rated | Round case | ±5% factory tolerance | Replaces HC98JA052 and GE\/Genteq 97F9971\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStart Capacitor Specs (P281-8806):\u003c\/strong\u003e 88–108 MFD | 330V | Round case | Includes bleed resistor — sold separately\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM capacitors are built to exact Carrier factory tolerances, ensuring reliable compressor startup and extended motor life.

Tools needed: 1\/4\" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Turn off power at the disconnect box and verify with a non-contact voltage tester before starting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.

Always verify the MFD and voltage ratings on your unit's data plate before ordering. Note: Carrier sources capacitors from third-party manufacturers — the label on the capacitor body will reflect the capacitor maker (e.g., Genteq, AmRad), not Carrier. This does not affect OEM fit or function. Have questions about fitment?
