Part numbers \u003cstrong\u003eP291-1003\u003c\/strong\u003e (10 MFD — condenser fan motor) and \u003cstrong\u003eP291-1503\u003c\/strong\u003e (15 MFD — compressor) are the Totaline\/Carrier Replacement Components Division capacitors originally installed at the factory. When either capacitor fails, you'll experience symptoms including a loud hum at startup with no motor movement, the system short-cycling within the first few minutes of operation, intermittent cooling or heating failure, or a tripped breaker caused by locked-rotor amperage draw. Replacing both at the same time is strongly recommended — if one has failed, the other is typically at the same age and stress level.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs — P291-1003 (Fan Motor Cap):\u003c\/strong\u003e 10 MFD (microfarad) | 370 VAC | Oval case | ±6% tolerance | 10,000 AFC protected | Non-PCB dielectric fluid | Operating range: -40°C to +70°C | 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs — P291-1503 (Compressor Cap):\u003c\/strong\u003e 15 MFD (microfarad) | 370 VAC | Oval case | ±6% tolerance | 10,000 AFC protected | Non-PCB dielectric fluid | UL-approved current interrupter | 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e These are Carrier Totaline Replacement Components Division capacitors — the same specification used on the factory line. Generic capacitors typically carry a ±10% MFD tolerance, which accelerates motor winding wear and reduces compressor service life. OEM-spec ±6% tolerance means tighter start and run performance across the full temperature range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Turn off power at the disconnect and wait a minimum of 5 minutes before touching any capacitor terminals (capacitors store lethal voltage even when power is off). Discharge with an insulated resistor before removal. Tools required: 1\/4\" nut driver, needle-nose pliers, multimeter (to verify residual charge and post-install MFD reading). Always photograph all wiring connections before disconnecting. Replace one capacitor at a time to avoid miswiring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty on both capacitors.

Verify MFD rating and voltage on your unit's data plate before ordering — do not substitute a higher or lower MFD value. Note that P291-1003 has been superseded by P291-1004 (440V-rated) and P291-1503 by P291-1504; both superseding parts are forward-compatible and may ship depending on current factory stock.
