OEM Carrier Single Run Capacitor 15 MFD 370V for Model PY2PNB042060NB

This OEM single run capacitor is the factory-specified replacement for the Carrier PY2PNB042060NB packaged unit. The run capacitor stores and releases the precise electrical charge needed to keep the compressor or condenser fan motor running efficiently at full speed. A failing capacitor typically causes a distinct hum with no motor startup, intermittent short-cycling, or a complete failure of the condenser fan or compressor — symptoms that will leave your system unable to cool or heat. Replacing with the correct OEM-spec part restores factory performance and protects downstream components from premature wear.

• Specs: 15 MFD (microfarad) | 370V rated | Oval case | Factory-matched ±5% tolerance | OEM Part Numbers: P291-0403 / P291-1503
• OEM vs Generic: OEM capacitors are manufactured to Carrier's exact electrical tolerances. Generic replacements can run ±10% MFD deviation, increasing motor heat and accelerating compressor wear — shortening the life of your most expensive components.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removal to ensure correct reinstallation.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.
