OEM Carrier Single Run Capacitor P291-0403 for Model PY1REA060115AAWB

This OEM single run capacitor is the factory-specified replacement for the Carrier PY1REA060115AAWB packaged unit. The run capacitor maintains the continuous phase shift necessary to keep the condenser fan motor or blower motor running efficiently after startup. A failing run capacitor typically causes the motor to hum without spinning, overheat under load, draw excessive amperage, or short-cycle — all of which can cascade into compressor damage if left unaddressed.

• Specs: OEM Part Number P291-0403 | Single run capacitor | Factory-matched MFD and voltage rating | Round or oval case per factory specification | ±3% tolerance for precise motor protection
• OEM vs Generic: This is a genuine OEM-spec Carrier capacitor manufactured to exact factory tolerances. Generic aftermarket capacitors commonly deviate ±10% MFD, increasing motor winding stress and reducing service life — especially critical on packaged rooftop units exposed to high ambient temperatures.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter with capacitance setting. Photograph all wiring connections before removal. Verify MFD and voltage ratings against your unit's data plate prior to installation.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for Carrier model PY1REA060115AAWB 5-ton packaged units. Always confirm the MFD rating and voltage printed on your existing capacitor against the data plate before ordering — capacitor specs can vary by production run. Have questions about fitment?
