OEM Carrier Single Run Capacitor 7.5 / 10 MFD 440V for Model 09DE054C900

This is the factory-specified OEM single run capacitor for the Carrier 09DE054C900, available in two MFD ratings to match your unit's data plate: P291-0754 (7.5 MFD) and P291-1004 (10 MFD). The run capacitor provides the continuous electrical charge required to keep the blower motor spinning efficiently throughout every heating and cooling cycle. When this component fails, symptoms include a humming motor that won't turn, the blower motor running hot and tripping thermal overload, or the motor failing to start entirely — leaving your system unable to circulate conditioned air.

• Specs: P291-0754 — 7.5 MFD ±6% | 440V | Oval case | 50/60 Hz | UL Listed & RoHS Compliant. P291-1004 — 10 MFD ±5% | 440V | Oval case | 50/60 Hz | UL Listed & RoHS Compliant.
• OEM vs Generic: These are genuine Carrier Totaline-brand capacitors engineered to ±5–6% MFD tolerance. Generic capacitors frequently run ±10% or wider, which accelerates motor winding wear and can shorten blower motor life significantly. Always match the MFD value on your unit's wiring diagram label exactly.
• Install difficulty: 1/5 — One of the easiest HVAC repairs. Tools needed: flathead screwdriver, needle-nose pliers, and a multimeter for pre-install verification. Critical safety step: discharge the capacitor terminals to ground with an insulated screwdriver before touching any leads. Photograph all wire connections before removal.
• Warranty & Shipping: 1-year OEM manufacturer warranty against defects. In stock and ships same business day from our warehouse. Oval form factor fits standard blower compartment mounting brackets on the Carrier 09DE054C900.

Compatibility & Ordering Note: Fits Carrier model 09DE054C900. Verify the MFD rating printed on your existing capacitor or the unit's wiring schematic before selecting between P291-0754 (7.5 MFD) and P291-1004 (10 MFD). P291-0754 directly replaces P291-0753 and HC91CA007. P291-1004 directly replaces P291-1003 and a wide range of cross-references including HC90BB010 and HC91DA010.
