The run capacitor provides the continuous phase-shifted electrical charge that keeps the compressor or fan motor spinning after startup. When this capacitor weakens or fails, you'll notice symptoms such as a loud humming with no motor movement, the system short-cycling off within minutes of startup, or a complete failure to start — even though the thermostat is calling for cooling or heating.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 15 MFD (microfarad) | 370V rated | Oval case | 50\/60 Hz | Non-PCB dielectric fluid | UL-approved current interrupter | Multiple electrical terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Totaline OEM capacitor manufactured to exact factory tolerances (±5% MFD). Generic aftermarket capacitors often run ±10% or wider, accelerating motor winding wear and reducing compressor life — a false economy on a critical component.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 1\/5\u003c\/strong\u003e — One of the easiest HVAC repairs.

Note that P291-1503 (370V) has been superseded by P291-1504 (440V) as the current OEM replacement — both share the same 15 MFD rating and are functionally interchangeable. Always verify the MFD rating and voltage on your unit's data plate before ordering. Have questions about fitment?
