OEM Carrier Dual Run Capacitor 45+7.5 MFD 370V for Model PH12NA03000GABAA

This OEM dual run capacitor is the factory-specified replacement for the Carrier PH12NA03000GABAA heat pump condenser. Sourced to OEM spec under part numbers P291-4573RS (superseded by P291-4574RS) and paired start capacitor P281-8806, this capacitor stores and releases the electrical charge required to start and sustain both the compressor (45 MFD) and the condenser fan motor (7.5 MFD). When a dual run capacitor fails, symptoms typically include a loud hum at startup with no motor movement, the compressor short-cycling off on thermal overload, or the condenser fan spinning freely by hand but failing to self-start under power.

• Specs: 45+7.5 MFD (microfarad) | 370V rated | Round case | Dual-section (compressor + fan) | Factory-matched ±5% tolerance | 50/60Hz rated
• OEM vs Generic: OEM capacitors are built to Carrier's exact factory tolerance specifications. Generic units commonly run ±10% MFD deviation, accelerating compressor wear, shortening motor life, and potentially voiding equipment warranties.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before removing any terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance mode. Photograph all wiring before disconnecting. Ensure power is locked out at the disconnect box before starting.
• Warranty & Shipping: 1-year OEM manufacturer warranty against defects. In stock and ships same business day from our warehouse. Free shipping on qualifying orders.

Compatibility: Engineered as a direct OEM fit for the Carrier PH12NA03000GABAA heat pump condenser. Also cross-references Carrier/Bryant/Payne part numbers HC98JA047 and GE Genteq model 97F9969. Always verify the MFD rating and voltage on your unit's data plate before ordering — if in doubt, our fitment team will confirm compatibility before you buy.
