OEM Carrier Dual Run Capacitor 45+5 MFD 370V for Model PH3GNA030000AB

This OEM dual run capacitor (part number P291-4553RS, superseded by P291-4554RS) is the factory-specified replacement for the Carrier PH3GNA030000AB air conditioner. The dual run capacitor provides the electrical charge needed to start and sustain both the compressor and the condenser fan motor simultaneously. When this component fails, you'll typically hear a low hum with no motor movement, notice the system short-cycling, or find the outdoor fan spinning slowly or not at all — leaving your home without cooling.

• Specs: 45+5 MFD (microfarad) | 370V rated | Round case | ±6% tolerance | 50/60 Hz | AFC: 10,000 | Castor oil protected | No PCBs | UL approved current interrupter
• OEM vs Generic: This OEM-spec capacitor meets exact factory tolerance requirements. Generic capacitors commonly run at ±10% MFD deviation, which accelerates wear on both the compressor and condenser fan motor, potentially voiding equipment warranties.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting the old unit. Follow all local electrical codes and shut off power at the disconnect box before beginning work.
• Warranty: 1-year manufacturer warranty. Orders ship same business day from our warehouse when placed before 3 PM local time.

Compatibility: Fits Carrier model PH3GNA030000AB. Note: P291-4553RS has been superseded by P291-4554RS — both carry identical 45+5 MFD 370V specifications. Always verify MFD and voltage ratings on your unit's data plate before ordering. Need fitment confirmation?
