A run capacitor maintains the steady phase shift needed to keep the motor spinning efficiently after startup. When it degrades or fails, you'll notice symptoms such as a loud hum with no motor movement, a compressor or fan that struggles to start, unexpected short-cycling, or a complete no-start condition — all of which can lead to costly secondary motor damage if left unaddressed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | OEM part number P291-1003 | Factory-matched capacitance and voltage rating | Designed to exact Carrier engineering tolerances (±3% or better)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM component — not an aftermarket substitute.
