OEM Carrier Dual Run Capacitor P291-8074R for Model PH13NB06100GBBAA

This is the factory-specified OEM dual run capacitor (part number P291-8074R) for the Carrier PH13NB06100GBBAA residential split-system air conditioner. The dual run capacitor performs a critical role in your system — it stores and releases the precise electrical charge required to start and continuously run both the compressor and the condenser fan motor simultaneously. When this capacitor begins to fail, common symptoms include a loud humming or buzzing sound with no motor movement, the compressor attempting to start and immediately tripping off on thermal overload, or the condenser fan spinning slowly or not at all. Left unaddressed, a weak or failed capacitor will overstress the compressor and fan motor, leading to far more costly repairs.

• Specs: OEM part number P291-8074R | Dual run (compressor + fan) | Factory-matched MFD and voltage rating | Round case design for easy drop-in replacement
• OEM vs Generic: This is a genuine OEM Carrier capacitor manufactured to exact factory tolerances (typically ±3% MFD). Generic or aftermarket capacitors often deviate ±10% or more, which accelerates wear on your compressor and fan motor windings and can void equipment warranties.
• Install Difficulty: 2/5 — A straightforward repair for experienced DIYers or any HVAC technician. Always discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting terminals.
• Warranty: Backed by a 1-year OEM factory warranty. Orders placed before 3PM ship same business day from our stocked warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier PH13NB06100GBBAA split-system condenser. Always verify the MFD rating and voltage printed on your existing capacitor's label or the unit's data plate before ordering to confirm an exact match. Have questions about fitment?
