Unlike a dual run capacitor, a single run capacitor is dedicated to one motor — either the compressor or the condenser fan — providing the precise phase-shifted electrical charge needed to start and sustain motor operation. When this capacitor weakens or fails, the affected motor may hum and refuse to start, trip its thermal overload, or cause the entire unit to short-cycle and shut down on a protection fault. Replacing it promptly prevents costly motor burnout.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e P291-1503 | Factory-matched MFD and voltage rating for the Carrier PH3PEA048000AA | Round or oval case (verify orientation on your unit's data plate)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM capacitor held to exact ±3% MFD tolerance.
