OEM Carrier Dual Run Capacitor 40+5 MFD 440V for Model PH4ZNA024000AA

This is the factory OEM dual run capacitor (part number P291-4054RS) specified for the Carrier PH4ZNA024000AA heat pump condenser. The dual run capacitor stores and releases the electrical charge needed to start and continuously run both the compressor and the condenser fan motor. When this capacitor weakens or fails, symptoms include a loud hum with no motor movement, the system short-cycling within minutes of startup, or the condenser fan spinning slowly or not at all. Replacing it promptly protects your compressor from hard-start damage.

• Specs: 40+5 MFD (microfarad) | 440V rated | Round case | ±6% capacitance tolerance | 50/60 Hz | AFC 10,000 | Castor oil protected | No PCB | UL approved
• OEM vs Generic: This is a genuine Carrier/Totaline OEM capacitor manufactured to factory specifications. Generic units often carry ±10% MFD tolerance, which accelerates compressor and motor wear. OEM ensures an exact electrical match to your PH4ZNA024000AA unit.
• Install difficulty: 2/5 — Always discharge the capacitor before touching terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Typical replacement time: 20–30 minutes.
• Warranty: 1-year OEM manufacturer warranty against defects. In-stock orders ship same business day from our warehouse.
