OEM Carrier Dual Run Capacitor 70+5 MFD 440V for Model PH4GNAB48000AA

This is the OEM factory-specified dual run capacitor for the Carrier PH4GNAB48000AA packaged heat pump unit, sold under Carrier part number P291-7054R. The dual run capacitor stores and releases the electrical charge required to start and sustain both the compressor and the condenser fan motor during every cooling and heating cycle. When this capacitor begins to fail, you'll notice symptoms such as a loud hum at startup with no motor movement, the compressor short-cycling off within minutes, the fan blade spinning only when manually nudged, or a complete failure of the outdoor unit to respond. Left unaddressed, a weak capacitor rapidly accelerates wear on both the compressor and fan motor — turning a $25 fix into a $500+ repair.

• Specs: 70+5 MFD (microfarad) | 440V rated | Round case | CBB65 class | Factory-matched ±3% tolerance for the Carrier PH4GNAB48000AA
• OEM vs Generic: This is a genuine Carrier OEM part (P291-7054R), built to exact factory tolerances. Generic capacitors often carry ±10% MFD variance, which accelerates motor winding stress and shortens compressor life. OEM is always the safest choice for a high-capacity 4-ton unit.
• Install Difficulty: 2/5 — Always shut off power at the disconnect and discharge the capacitor fully before touching terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting. Swap terminals one at a time to avoid miswiring.
• Warranty & Shipping: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse.

Compatibility: Designed as the direct OEM replacement for the Carrier PH4GNAB48000AA packaged heat pump. This part also replaces superseded part numbers HC98KA071, P291-7053RS, and P291-7073RS. Always verify the MFD and voltage rating on your unit's data plate before ordering. Our HVAC parts team is available to confirm fitment — just reach out before you buy.
