OEM Carrier Dual Run Capacitor 50+7.5 MFD 370V for Model PH13NR036000AFAA

This is the factory-specified OEM dual run capacitor (part number P291-5073RS) for the Carrier PH13NR036000AFAA 3-ton split-system heat pump. The dual run capacitor stores and releases the electrical charge needed to start and sustain both the compressor and the condenser fan motor simultaneously. When it fails, you'll hear a telltale hum with no motor movement, notice the system short-cycling, or find the outdoor unit completely unresponsive — all classic signs of capacitor failure. A companion start capacitor (P281-8806, 88–108 MFD / 330V) is also available and recommended for inspection any time the dual run cap is replaced.

• Dual Run Capacitor Specs (P291-5073RS): 50+7.5 MFD (microfarad) | 370V rated | Round case | ±5% factory tolerance | Replaces HC98JA052 and GE/Genteq 97F9971
• Start Capacitor Specs (P281-8806): 88–108 MFD | 330V | Round case | Includes bleed resistor — sold separately
• OEM vs Generic: OEM capacitors are built to exact Carrier factory tolerances, ensuring reliable compressor startup and extended motor life. Generic units often carry a ±10% MFD variance, which accelerates wear on the compressor windings and shortens equipment lifespan.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals (use a 10kΩ resistor or insulated screwdriver). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Turn off power at the disconnect box and verify with a non-contact voltage tester before starting.
• Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier PH13NR036000AFAA 3-ton heat pump. Always verify the MFD and voltage ratings on your unit's data plate before ordering. Note: Carrier sources capacitors from third-party manufacturers — the label on the capacitor body will reflect the capacitor maker (e.g., Genteq, AmRad), not Carrier. This does not affect OEM fit or function. Have questions about fitment? Our HVAC parts specialists verify compatibility before you order — reach out before you buy.
