OEM Carrier Dual Run Capacitor 70+7.5 MFD 370V for Model PH14NA04800GBAAA

This OEM dual run capacitor is the factory-specified replacement for the Carrier PH14NA04800GBAAA heat pump condenser. The dual run capacitor stores and delivers the electrical charge required to start and sustain both the compressor and condenser fan motor simultaneously. When this component weakens or fails, you'll notice symptoms such as the compressor humming without starting, the condenser fan failing to spin, the system short-cycling, or a complete no-cooling condition. This unit ships under OEM part number P291-7073RS (superseded by P291-7074R), both of which are fully interchangeable on your PH14NA04800GBAAA. The system also uses a companion start capacitor P281-1766 (175–216 MFD, 330V) — if your compressor is struggling to start, replacing both together is best practice and eliminates a second service call.

• Specs — Dual Run Capacitor (P291-7073RS / P291-7074R): 70+7.5 MFD (microfarad) | 370V rated (440V compatible) | Round case, 2.5" diameter | ±6% tolerance | RoHS Compliant | UL Approved | Castor oil protected, no PCB | Tested to 60,000 service hours
• OEM vs Generic: OEM Totaline/Carrier capacitors are manufactured to exact factory tolerance (±6%), ensuring proper compressor and fan motor operation. Generic aftermarket capacitors often carry ±10% MFD variance, which accelerates motor winding stress and shortens compressor life — especially critical on a 4-ton heat pump running long cycles.
• Install difficulty: 2/5 — Always discharge the capacitor before touching any terminals (use an insulated resistor or screwdriver across terminals). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance function). Photograph all wire connections before removal. Takes approximately 20–30 minutes.
• Warranty & Shipping: 1-year OEM manufacturer warranty against defects. In stock and ships same business day from our warehouse when ordered before 3PM local time.

Compatibility: Fits Carrier model PH14NA04800GBAAA heat pump condensers. OEM part numbers P291-7073RS and its direct successor P291-7074R are fully interchangeable. Also cross-references GE/Genteq C37075R and 27L556. Always verify the MFD and voltage rating on your unit's data plate before ordering — our team is available to confirm fitment.
