OEM Carrier Dual Run Capacitor 70+7.5 MFD 370V for Model PH4GNAA60000AA

This OEM dual run capacitor (part number P291-7073RS) is the factory-specified replacement for the Carrier PH4GNAA60000AA heat pump system. The dual run capacitor serves a critical role in your HVAC system — it stores and releases the electrical charge needed to both start and continuously run the compressor and condenser fan motor simultaneously. When this capacitor degrades or fails, you'll typically notice symptoms such as a loud humming with no motor movement, the outdoor unit failing to start entirely, or the system short-cycling and shutting down within minutes of operation. Left unaddressed, a failing capacitor places enormous strain on the compressor, potentially leading to a far more costly repair.

• Specs: 70+7.5 MFD (microfarad) | 370V rated (440V-compatible upgrades accepted) | Round case | ±6% factory tolerance | 50/60 Hz | Castor oil protected | No-PCB construction
• OEM vs Generic: This OEM-spec capacitor is built to Carrier's exact factory tolerance of ±6% MFD. Generic aftermarket capacitors often run ±10% or wider, causing premature motor wear, increased compressor amperage draw, and shortened equipment life — especially critical on a high-demand 5-ton system like the PH4GNAA60000AA.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Match MFD ratings exactly — do not substitute with a different MFD value.
• Warranty & Shipping: 1-year OEM warranty coverage. Ships same business day from our warehouse. Questions about fitment? Our team verifies compatibility before you order — just reach out.

Compatibility: Designed for the Carrier PH4GNAA60000AA heat pump condenser. Cross-references include HC98JA072, E187356, P2917073RS, and Genteq/GE model 27L556 (C37075R). Note: OEM part P291-7073RS has been superseded by P291-7074R — this listing ships the current production equivalent.
