OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY2PNB060115NB

This is the factory-specified OEM single run capacitor for the Carrier PY2PNB060115NB packaged unit. The run capacitor remains energized throughout the entire operating cycle of the condenser fan motor, improving efficiency and sustaining steady motor rotation. When this capacitor weakens or fails, you'll typically notice the fan motor humming without spinning, the unit short-cycling due to thermal overload, or a complete no-start condition with no cooling output. OEM part numbers covered by this listing: P291-0403 and cross-reference P291-2503.

• Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case | ±6% factory tolerance | 50/60 Hz | UL approved | RoHS compliant | Non-PCB dielectric fluid
• OEM vs Generic: This genuine Carrier Totaline capacitor is reliability-tested to 60,000 service hours and subjected to 100% electrical testing at the factory — including capacitance, power factor, dissipation factor, and high-voltage withstand. Generic capacitors often run wide tolerance bands, accelerating motor wear and shortening run life.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance function. Photograph all wiring connections before disconnecting. Verify MFD and voltage rating on your unit's data plate before installation.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
