A single run capacitor provides the sustained electrical charge required to keep the compressor or fan motor running at peak efficiency. When this capacitor degrades or fails, common symptoms include a humming sound with no motor movement, the system tripping on high-pressure lockout, hard-start conditions, or the unit short-cycling shortly after startup. Replacing it with the correct OEM part ensures factory-matched performance and protects downstream components.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part Number P291-1503 | Single run capacitor | Factory-matched MFD and voltage rating | Engineered to exact factory tolerance (±5%) for the Carrier PH3PEA036000AA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is manufactured to Carrier's exact electrical specifications.
