OEM Carrier Single Run Capacitor P291-0753 for Model YAC:48/140YAC-104C–

This OEM single run capacitor (Part No. P291-0753) is the factory-specified replacement for the Carrier YAC:48/140YAC-104C– packaged unit. A single run capacitor continuously supplies the phase-shifted electrical charge required to keep either the compressor or the fan motor running at peak efficiency. When this capacitor degrades or fails, you may notice symptoms such as a humming unit that won't start, a compressor or fan motor that kicks off within seconds, or the system tripping on thermal overload due to motor strain.

• Specs: Single run capacitor | OEM part number P291-0753 | Factory-matched MFD and voltage rating | Designed for Carrier YAC:48/140YAC-104C– packaged systems
• OEM vs Generic: This OEM unit is manufactured to exact Carrier factory tolerances (typically ±3% MFD). Aftermarket alternatives often run ±10% tolerance, which increases motor amp draw, accelerates bearing wear, and can void equipment warranties.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling. Required tools: 1/4″ nut driver, needle-nose pliers, and a multimeter (capacitance setting). Photograph all wiring connections before disconnecting the old unit.
• Warranty: 1-year OEM factory warranty included. Orders placed before cutoff ship the same business day from our climate-controlled warehouse.

Compatibility: Engineered specifically for the Carrier YAC:48/140YAC-104C– packaged unit. Always verify the MFD and voltage ratings printed on your existing capacitor or equipment data plate before ordering to ensure a direct fit. Not sure?
