The run capacitor provides the continuous phase-shifted current necessary to keep the blower or condenser fan motor running at peak efficiency. When this capacitor degrades or fails, you'll typically notice symptoms such as the motor humming without spinning, the system short-cycling due to thermal overload, sluggish motor startup, or a complete motor no-start condition — all of which can rapidly escalate to full motor burnout if left unaddressed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | Factory OEM-matched MFD rating | 370V\/440V rated | Cylindrical case | Tight ±3% capacitance tolerance for optimal motor performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier part (P291-1003), manufactured to exact factory specifications.
