OEM Carrier Single Run Capacitor 15 MFD 370V for Model PY1REA048074AAWA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY1REA048074AAWA system. Supplied under Carrier/Totaline OEM part numbers P291-1503 and P291-0403, this oval-case run capacitor maintains the continuous phase-shifted current that keeps your condenser fan motor or compressor running smoothly at rated efficiency. When a run capacitor degrades or fails, you'll notice symptoms such as the motor struggling to start, humming without spinning, short-cycling, or the unit tripping on high-pressure lockout due to inadequate airflow or compression.

• Specs: 15 MFD (microfarad) | 370V rated | Oval case | Factory-matched ±5% capacitance tolerance | Metallized polypropylene film dielectric | RoHS compliant
• OEM vs Generic: OEM Carrier/Totaline capacitors are reliability-tested to 60,000 service hours and subjected to 100% electrical testing at the factory. Generic units often lack tight MFD tolerance control, accelerating motor winding wear and shortening equipment life.
• Install difficulty: 2/5 — Always discharge the capacitor fully before removing terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Verify MFD and voltage ratings on the unit's data plate before installing.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for Carrier model PY1REA048074AAWA. Part numbers P291-1503 and P291-0403 are Carrier/Totaline factory authorized parts. Note: P291-1503 has been superseded — this listing ships the current authorized equivalent. Always verify MFD rating and voltage on your unit's data plate before ordering.
