OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY2PNB060115AB

This OEM single run capacitor is the factory-specified replacement for the Carrier PY2PNB060115AB system. The run capacitor maintains the continuous phase shift needed to keep the motor spinning efficiently during normal operation. When this capacitor weakens or fails, you'll typically notice the motor humming without starting, the unit short-cycling, or a complete no-start condition that leaves the system unresponsive on a call for cooling or heating.

• Specs: 4 MFD (microfarad) | 370V rated | Oval case | ±5% factory tolerance | Totaline/Carrier OEM series | Replaces P291-0403 and P291-2503
• OEM vs Generic: Carrier Totaline OEM capacitors are reliability-tested to 60,000 service hours per United Technologies application parameters and feature high-grade metallized polypropylene film. Generic units often deviate ±10% MFD, accelerating motor wear over time.
• Install difficulty: 2/5 — Always discharge the capacitor fully before touching any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Verify MFD and voltage on your unit's data plate before installing.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before 3PM local time.

Compatibility: Engineered as the direct OEM replacement for Carrier model PY2PNB060115AB. Cross-references OEM part numbers P291-0403 and P291-2503 (Totaline/Carrier Oval Run Capacitor, 4 MFD, 370V). Always verify the MFD rating and voltage on your unit's data plate before ordering. Questions about fitment?
