OEM Carrier Single Run Capacitor for Model YAC48110YAC103AT

This OEM single run capacitor is the factory-specified replacement for the Carrier YAC48110YAC103AT packaged unit. A single run capacitor maintains a continuous phase-shifted current to keep the motor running at peak efficiency after startup. When this capacitor fails, you'll typically notice symptoms such as a humming unit that won't fully start, a compressor or fan motor that short-cycles within minutes, or a system that trips on high-pressure lockout due to a struggling motor. Replacing a worn or failed capacitor promptly prevents costly downstream damage to your compressor.

• OEM Part Numbers: P291-0753 | P291-4504 — both are factory-authorized replacements for the Carrier YAC48110YAC103AT; verify your unit's data plate for the exact MFD and voltage rating before ordering.
• OEM vs Generic: OEM capacitors are manufactured to exact factory tolerances (typically ±3% MFD), ensuring optimal motor performance and longevity. Generic alternatives often carry a ±10% tolerance, which can accelerate motor winding wear and shorten overall equipment life.
• Install Difficulty: 2/5 — Always disconnect power and discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, and a multimeter capable of capacitance testing. Photograph all wiring connections before removal.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered for the Carrier YAC48110YAC103AT packaged unit. Always cross-reference the MFD value and voltage rating printed on the original capacitor or the unit's data plate to confirm fitment. Need help verifying your part? Our HVAC specialists confirm fitment before you order — no guesswork.
