OEM Carrier Single Run Capacitor 7.5 MFD 370V for Model YAC2480YACX506T

This is the factory-specified OEM single run capacitor for the Carrier YAC2480YACX506T air conditioning unit, listed under OEM part numbers P291-0753 and P291-3503. The run capacitor stays energized throughout motor operation, providing the sustained phase-shifted current that keeps the condenser fan motor or compressor spinning at peak efficiency. When it weakens or fails, you'll typically notice the motor humming without starting, the unit short-cycling, or a complete no-start condition — symptoms that worsen fast on hot days and can lead to motor burnout if left unaddressed.

• Specs: 7.5 MFD (microfarad) | 370V rated (440V-compatible replacement accepted) | Oval can case | ±5% factory tolerance | UL approved current interrupter | Non-PCB dielectric fluid | 50/60 Hz
• OEM vs Generic: This OEM capacitor is manufactured to Carrier's exact factory specification. Generic capacitors frequently run outside ±6% MFD tolerance, increasing motor amp draw, generating excess heat, and shortening both motor and compressor life significantly.
• Install difficulty: 2/5 — Always disconnect power at the disconnect box before servicing. Capacitors store a charge even when power is off — discharge terminals with an insulated screwdriver before handling. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance function. Photograph all wiring connections before removing old capacitor.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered for Carrier model YAC2480YACX506T. Cross-references include OEM part numbers P291-0753, P291-3503, HC91CA007, GE/Genteq 27L566, and successor P291-0754. Always verify the MFD rating and voltage on your unit's data plate before ordering — never substitute a lower MFD value, and never use a lower voltage rating than specified. Questions about fitment?
