OEM Carrier Dual Run Capacitor P291-5073RS for Model PH11JA036000AAAA

This OEM dual run capacitor (part number P291-5073RS) is the factory-specified replacement for the Carrier PH11JA036000AAAA heat pump system. The dual run capacitor stores and releases the precise electrical charge required to start and continuously run both the compressor and the condenser fan motor from a single unit. Common failure symptoms include a loud humming with no motor movement, the compressor attempting to start and immediately tripping, the condenser fan spinning only when manually nudged, or the system short-cycling shortly after startup — all signs pointing to a weak or failed capacitor.

• Specs: OEM Part No. P291-5073RS | Dual run configuration (compressor + fan) | Factory-matched MFD and voltage rating | Round case design | ±3% tolerance to factory specification
• OEM vs Generic: This is a genuine OEM Carrier capacitor, manufactured to exact factory tolerances. Generic aftermarket capacitors frequently run ±10% MFD deviation, which accelerates compressor and fan motor wear over time and can void equipment warranties.
• Install Difficulty: 2/5 — Intermediate DIY-friendly replacement. Always disconnect power at the breaker and discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections before removal.
• Warranty: Backed by a 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier PH11JA036000AAAA heat pump.
