The run capacitor provides the continuous phase-shifted current required to keep the blower motor spinning efficiently after startup. When this capacitor degrades or fails, you'll typically notice symptoms such as a humming motor that won't spin, sluggish blower startup, intermittent shutdowns, or a complete loss of airflow — all signs of a capacitor that can no longer hold its rated charge.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | Factory-rated MFD and voltage per OEM specification | Oval or round case (verify data plate) | ±5% tolerance to match original factory performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier part, manufactured to exact factory tolerances.
