OEM Carrier Dual Run Capacitor P291-3553RS for Model PH3PNA024000AA

This OEM dual run capacitor (part number P291-3553RS) is the factory-specified replacement for Carrier model PH3PNA024000AA heat pump systems. The dual run capacitor stores and releases the electrical charge required to start and continuously run both the compressor and the condenser fan motor from a single component. Common failure symptoms include an audible hum with no motor movement, the system failing to start, short-cycling within the first few minutes of operation, or a tripped breaker caused by locked-rotor current draw.

• Specs: OEM-matched MFD rating | 370V/440V rated (verify data plate) | Round case form factor | Factory-matched ±5% tolerance for compressor and fan motor protection
• OEM vs Generic: This listing supplies the genuine OEM P291-3553RS capacitor. Generic alternatives (such as P291-1503 single run) are available but may carry wider MFD tolerance (±10%), increasing wear on the compressor and shortening motor life over time. OEM is always the recommended choice for warranty-active or newer systems.
• Install Difficulty: 2/5 — Always disconnect power at the breaker and discharge the capacitor terminals before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before removal to ensure correct reinstallation.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse when ordered before 3 PM local time.
