The run capacitor maintains a continuous phase-shifted current to keep the blower or condenser fan motor running at full efficiency after startup. When it degrades or fails, you'll typically notice symptoms such as a humming motor that won't spin, the unit failing to cool, or the system shutting down on thermal overload shortly after startup — all classic signs of a capacitor losing its microfarad rating.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 15 MFD (microfarad) | 370V rated | Oval case | Factory-matched ±5% tolerance | OEM part number P291-1503\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the factory-authorized OEM capacitor, built to exact Carrier tolerances.
