OEM Carrier Dual Run Capacitor 50+5 MFD 440V for Model PH10JA048000ABAA

This OEM dual run capacitor (part# P291-5054RS) is the factory-specified replacement for the Carrier PH10JA048000ABAA heat pump. The dual run capacitor stores and releases the electrical charge needed to start and continuously run both the compressor and the condenser fan motor simultaneously. When this component fails, symptoms typically include a loud hum with no compressor or fan startup, the system short-cycling within the first few minutes of operation, or a complete failure of the outdoor unit to respond — all of which can quickly cascade into compressor damage if left unaddressed.

• Specs: 50+5 MFD (microfarad) | 370/440V dual-rated | Round case | ±3% factory tolerance | 50/60 Hz | RoHS compliant | UL approved
• OEM vs Generic: This is the genuine Carrier/Totaline OEM part, tested to 60,000 service hours. Generic capacitors often carry a ±10% MFD tolerance, increasing stress on the compressor windings and shortening motor life significantly.
• Install difficulty: 2/5 — Always discharge the capacitor before handling terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Three terminals labeled HERM, FAN, and C (common).
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
