The dual run capacitor provides the start and run boost required by both the compressor and condenser fan motor within a single round case. When this component fails, you'll typically notice a loud humming with no motor movement, a system that trips the breaker shortly after startup, or a condenser fan that spins only when manually assisted — all signs of imminent compressor damage if left unaddressed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40+5 MFD (microfarad) | 440V rated | Round case | OEM part number P291-4054RS | Factory-matched ±3% tolerance for precise motor performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier capacitor engineered to exact factory tolerances.
