OEM Carrier Dual Run Capacitor (P291-4573RS) & Start Capacitor (P281-8806) for Model PH13NR030000AFAA

This factory-matched capacitor kit includes both the dual run capacitor (P291-4573RS) and the start capacitor (P281-8806) specified for the Carrier PH13NR030000AFAA heat pump condenser. The dual run capacitor continuously supplies the phase-shifted current required to keep the compressor and condenser fan motor running. The start capacitor delivers a high-torque boost at startup to get the compressor spinning under load. When either capacitor degrades, you'll experience symptoms ranging from a humming compressor that won't start, frequent short-cycling, tripped breakers, or a complete no-cooling condition — often on the hottest day of the year.

• Dual Run Capacitor Specs (P291-4573RS): 45 + 7.5 MFD (microfarad) | 370 VAC | Round case | Factory ±3% tolerance | Replaces HC98JA047, GE 97F9969
• Start Capacitor Specs (P281-8806): 88–108 MFD | 330 VAC | Round case with bleed resistor | Genuine Carrier Totaline OEM
• OEM vs Generic: OEM capacitors are reliability-tested to 60,000 service hours per Carrier application parameters and use high-grade metallized polypropylene film. Generic units often ship with ±10% MFD tolerance, accelerating compressor wear and voiding equipment warranties.
• Install Difficulty: 2/5 — Always discharge capacitors before touching terminals (stored charge can exceed 370V). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance mode. Photograph all wiring before disconnecting. Verify MFD and voltage ratings on your unit's data plate before installation.
• Warranty: 1-year OEM factory warranty on both capacitors. Orders ship same business day from our warehouse.

Compatibility: Engineered for the Carrier PH13NR030000AFAA heat pump condenser. Note: P291-4573RS has been superseded by P291-4574RS (440V upgrade) — both are fully compatible. Verify MFD ratings on your existing capacitors before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required.
