OEM Carrier Dual Run Capacitor 70+7.5 MFD 370V for Model PH15NA060000BAAA

This OEM dual run capacitor (P291-7073RS / superseded by P291-7074R) is the factory-specified replacement for the Carrier PH15NA060000BAAA 5-ton packaged heat pump. The dual run capacitor simultaneously powers both the compressor and the condenser fan motor, storing and releasing the electrical charge required to start and sustain each motor's operation. When this capacitor degrades or fails, you'll typically experience a loud hum from the condenser with no motor movement, intermittent short-cycling, or complete failure of the outdoor unit to start on a call for cooling or heating.

• Specs: 70+7.5 MFD (microfarad) | 370V rated | Round case, 2.5" diameter | ±6% tolerance | 50/60 Hz | RoHS compliant | UL approved with pressure-sensitive interrupter | Castor oil protected, No-PCB construction | OEM Part Numbers: P291-7073RS (original) / P291-7074R (current superseding part) | Also includes start capacitor P281-1766: 175–216 MFD, 330V
• OEM vs Generic: This factory Totaline/Carrier capacitor is engineered to ±6% MFD tolerance and tested to 60,000 service hours under Carrier's own reliability standards. Generic aftermarket capacitors commonly run ±10% tolerance, which accelerates compressor wear and shortens system life — particularly critical on a 5-ton unit where the compressor load is high.
• Install difficulty: 2/5 — Always discharge the capacitor fully before touching any terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all terminal wiring before disconnecting — the HERM, FAN, and COM terminals must be correctly reconnected. Turn off power at the disconnect before beginning.
• Warranty & Shipping: 1-year OEM manufacturer warranty against defects. In stock — ships same business day from our warehouse.

Compatibility: Fits Carrier model PH15NA060000BAAA 5-ton packaged heat pump.
