The run capacitor maintains a continuous phase-shifted current to the blower or condenser fan motor, keeping it spinning efficiently at full torque after startup. When the capacitor degrades or fails, you'll notice symptoms like a humming motor that won't turn over, a fan that spins slowly or only when manually assisted, or a unit that trips on high-limit and short-cycles due to reduced airflow caused by an underperforming blower motor.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | Factory-matched MFD and voltage rating | Cylindrical case | OEM-grade ±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 part (P291-1003), manufactured to exact factory specifications.
