OEM Carrier Dual Run Capacitor 70+5 MFD 440V for Model PH4ZNA048000AA

This OEM dual run capacitor (Part# P291-7054R) is the factory-specified replacement for the Carrier PH4ZNA048000AA heat pump condenser. The dual run capacitor stores and delivers the electrical charge needed to start and sustain both the compressor and condenser fan motor simultaneously. When this component weakens or fails, you'll typically notice the unit humming without the compressor or fan spinning, the system tripping on high-pressure lockout, or the condenser short-cycling within minutes of startup — all classic signs of capacitor failure on 4-ton Carrier heat pump systems.

• Specs: 70+5 MFD (microfarad) | 440V rated | Round case | 50/60 Hz | ¼" quick-disconnect terminals | Factory-matched ±5% tolerance | UL approved
• OEM vs Generic: This is a genuine Carrier Totaline OEM capacitor engineered to meet factory tolerance specifications. Generic capacitors often ship at ±10% MFD tolerance, which accelerates compressor wear, shortens motor life, and can void system warranties.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: ¼" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all terminal wiring before disconnecting. The 70 MFD side feeds the compressor; the 5 MFD side feeds the fan motor — do not swap leads.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH4ZNA048000AA heat pump condenser unit. Also replaces superseded part numbers HC98KA071, P291-7053RS, and P291-7073RS. Always verify the MFD rating and voltage on your unit's data plate before ordering to ensure correct fitment. Have a question? Our HVAC parts specialists verify fitment before you buy — reach out before placing your order.
