The run capacitor maintains the continuous phase-shifted voltage that keeps the blower or condenser fan motor running smoothly after startup. When this component degrades or fails, you'll notice symptoms such as a humming motor that won't spin, intermittent short-cycling, overheating, or a complete no-start condition — all of which can cascade into compressor or motor damage if left unaddressed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | Factory-rated MFD and voltage — verify against your unit's data plate | Designed for exact OEM fit and terminal compatibility with Carrier PG8MAA042090AAJA\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 ±3% MFD tolerance.
