OEM Carrier Single Run Capacitor 7.5 MFD 370V for Model U19X125U48A

This is the factory-specified OEM single run capacitor for the Carrier U19X125U48A unit, Carrier part number P291-0753. The run capacitor maintains a continuous phase-shifted current to keep the condenser fan motor spinning at full efficiency after startup. When this capacitor degrades or fails, you'll typically notice the fan motor humming without spinning, the system overheating and tripping on high-pressure lockout, or the unit short-cycling. Replacing it promptly protects your compressor from the heat damage caused by restricted airflow.

• Specs: 7.5 MFD (microfarad) | 370V rated | Oval case | ±5% factory tolerance | Cross-references: HC91CA007, GE 27L566, Genteq C307L
• OEM vs Generic: OEM capacitors are manufactured to Carrier's exact tolerance specifications. Generic alternatives often run ±10% MFD deviation, which shortens motor winding life and can void equipment warranties.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before touching terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wire connections before removal.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our stocked warehouse.

Compatibility Note: Engineered for Carrier model U19X125U48A. Verify the MFD rating and voltage on your unit's data plate before ordering — voltage rating must be equal to or higher than the original. Note: Carrier has superseded P291-0753 with P291-0754 (440V); both 370V and 440V variants are compatible, as a higher voltage rating is a safe upgrade.
