OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY2PNB060130NB

This OEM single run capacitor (part numbers P291-0403 and P291-2503) is the factory-specified replacement for the Carrier PY2PNB060130NB packaged unit. The run capacitor stores and delivers the electrical charge required to keep the condenser fan motor running at rated efficiency. When this capacitor degrades or fails, you'll typically experience symptoms such as a humming motor that won't spin up, the system short-cycling due to overheating, or a complete loss of airflow from the condenser section.

• Specs: 4 MFD (microfarad) | 370V rated | Oval case form factor | Factory ±5% capacitance tolerance | 50/60 Hz compatible
• OEM vs Generic: This is a genuine Carrier Totaline OEM capacitor — reliability tested to 60,000 service hours per United Technologies parameters, built with high-grade metallized polypropylene film, and subjected to 100% electrical testing before packaging. Generic capacitors typically carry wider tolerance bands (±10%), accelerating motor wear over time.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling. Tools needed: flathead screwdriver, needle-nose pliers, multimeter (capacitance mode). Photograph all terminal wiring before disconnecting. Match MFD and voltage ratings exactly to your unit's data plate.
• Warranty & Shipping: 1-year OEM manufacturer warranty. UL Approved with patented pressure-sensitive interrupter. RoHS compliant. In stock — ships same business day from our warehouse.

Compatibility: Engineered for Carrier model PY2PNB060130NB. OEM part numbers P291-0403 and P291-2503 — also cross-references GE/Genteq C304L and 27L571. Verify the MFD rating and voltage on your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy.
