A run capacitor provides the continuous phase-shifted electrical boost that keeps either the compressor or condenser fan motor spinning at full efficiency. When it fails, you'll typically notice a loud humming with no motor movement, intermittent shutdowns, or a complete no-start condition — all signs the capacitor can no longer hold its charge.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | Factory-matched MFD rating | 370V or 440V rated (verify on unit data plate) | Cylindrical case | OEM-spec ±5% tolerance for precise motor protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier capacitor built to exact factory specifications. Generic alternatives often carry a wider ±10% MFD tolerance, which can accelerate motor winding stress and reduce compressor lifespan over time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Always discharge the capacitor fully before handling — it can hold a lethal charge even when power is off. Tools needed: insulated screwdriver, 1\/4\" nut driver, needle-nose pliers, and a multimeter to verify discharge.
