OEM Carrier Single Run Capacitor 15 MFD 370V for Model PH2PPB036000AA

This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Carrier PH2PPB036000AA heat pump system. The run capacitor provides the continuous phase-shifted current that keeps the condenser fan motor or compressor spinning at full efficiency after startup. A failing run capacitor typically presents as a humming unit that won't start, a motor that labors and overheats, or a system that trips on thermal overload and short-cycles within minutes of operation — all signs that immediate replacement is needed to avoid cascading compressor damage.

• Specs: 15 MFD (microfarad) | 370V rated | Oval case | 50/60 Hz | Non-PCB dielectric fluid | UL-approved current interrupter | Multiple electrical terminals
• OEM vs Generic: This is a genuine Carrier/Totaline OEM unit manufactured to exact factory tolerance (±5% MFD). Generic capacitors commonly run ±10% or worse, accelerating motor wear and increasing the risk of premature compressor failure on your PH2PPB036000AA.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before removal. Total job time: 15–30 minutes for most homeowners.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed for the Carrier PH2PPB036000AA heat pump condensing unit. Note: Carrier sources capacitors from third-party manufacturers such as Totaline — the label on the physical capacitor will reflect the component manufacturer's name, not Carrier. Always verify the MFD rating and voltage on your unit's data plate before ordering. Have a fitment question?
