OEM Carrier Single Run Capacitor 4 MFD 370V Oval for Model PY2PPB060130NB

This OEM single run capacitor is the factory-specified replacement for the Carrier PY2PPB060130NB packaged unit. The run capacitor maintains a continuous phase-shifted current to keep the fan motor spinning at the correct speed and torque after startup. When it fails, symptoms include a humming fan motor that won't turn, the unit short-cycling within minutes of startup, or a complete loss of airflow with the compressor still running — all of which can quickly lead to compressor overheating and costly secondary damage if left unaddressed.

• Specs: 4 MFD (microfarad) | 370V rated | Oval case | ±6% factory tolerance | 50/60 Hz | Replaces OEM part numbers P291-0403, P291-1003, and P291-2503
• OEM vs Generic: This Totaline/Carrier OEM capacitor is tested to 60,000 service hours and uses high-grade metallized polypropylene film with a UL-approved pressure-sensitive interrupter. Generic alternatives often run wider MFD tolerances (±10% or more), accelerating motor wear and shortening equipment life. Every unit is subjected to 100% electrical testing before leaving the factory.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals — a charged capacitor can deliver a dangerous shock. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph existing wiring before disconnecting. Verify MFD and voltage ratings on the unit data plate before installation.
• Warranty & Shipping: 1-year OEM manufacturer warranty. In stock — ships same business day from our warehouse. RoHS compliant.

Compatibility: Designed for Carrier model PY2PPB060130NB packaged unit. Supersedes OEM part numbers P291-0403, P291-1003, and P291-2503.
