The run capacitor provides the sustained phase-shifted current that keeps the blower motor spinning at correct speed and efficiency. When the capacitor degrades or fails, you'll typically notice the blower motor humming without starting, the system shutting down on high-limit due to poor airflow, or sluggish motor ramp-up that causes erratic heating cycles.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40 MFD (microfarad) | 370V AC rated | Single run, oval case | ±5% factory tolerance | 50\/60 Hz | OEM Part Number: P291-4003\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM-spec capacitor is manufactured to Carrier's exact tolerance and dielectric standards.
