OEM Carrier Single Run Capacitor P291-0753 for Model YAC48110YAC203AT

This OEM single run capacitor (part number P291-0753) is the factory-specified replacement for the Carrier YAC48110YAC203AT packaged unit. A single run capacitor provides the continuous phase-shifted current needed to keep either the compressor motor or the condenser fan motor running efficiently after start-up. When this capacitor degrades or fails, you'll typically notice symptoms such as a humming unit that won't start, a motor that shuts off within seconds of energizing, increased amp draw on the motor circuit, or complete loss of cooling output.

• Specs: OEM single run capacitor | Factory-matched MFD rating and voltage | Cylindrical case design | Meets or exceeds original Carrier factory tolerances (±3% MFD)
• OEM vs Generic: This is a genuine OEM Carrier replacement (P291-0753), engineered to exact factory specifications. Generic capacitors are often rated at ±10% MFD tolerance, which accelerates motor winding stress and can shorten compressor or fan motor lifespan significantly.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before disconnecting any terminals — stored voltage can cause serious injury. Tools needed: insulated screwdriver, 1/4" nut driver, needle-nose pliers, and a multimeter for post-install verification. Photograph all wiring connections before removal.
• Warranty: Covered by a 1-year OEM factory warranty. In-stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Designed specifically for the Carrier YAC48110YAC203AT packaged unit. Always verify the MFD rating and voltage printed on your existing capacitor's label or your unit's wiring diagram before ordering to ensure an exact match.
