A single run capacitor provides the continuous electrical charge required to keep the motor running after startup — whether that's the condenser fan motor or the compressor. When this component fails, you'll notice symptoms such as a humming unit that won't start, a motor that runs hot and shuts off on thermal overload, or a system that trips the breaker shortly after startup. Replacing a failed run capacitor promptly prevents secondary damage to motors and compressors, which are far more costly to replace.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | OEM part number P291-1503 | Factory-matched MFD and voltage rating | Round case design | ±5% tolerance for precise motor protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM capacitor, not an aftermarket substitute. OEM units are manufactured to exact factory tolerances, ensuring proper motor run current and extended service life. Generic capacitors often carry ±10% MFD tolerances that can accelerate motor winding wear over time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — A single run capacitor is one of the more straightforward HVAC repairs. Required tools: 1\/4\" nut driver, insulated needle-nose pliers, and a multimeter capable of capacitance testing. Always discharge the capacitor fully before handling terminals, and photograph all wiring connections before removal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Backed by a 1-year OEM factory warranty.
