OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY3PNA024060NA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY3PNA024060NA system. The run capacitor remains in the circuit the entire time the fan motor or compressor is operating, stabilizing voltage and ensuring efficient motor performance. When it degrades or fails, common symptoms include a humming or buzzing sound with no motor movement, a fan motor that won't start, or a unit that short-cycles and shuts down shortly after starting. Replacing it promptly with the correct OEM part prevents secondary damage to the compressor and fan motor.

• Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case form factor | ±5% factory tolerance | 50/60 Hz | Part numbers: P291-0403 / P291-1503
• OEM vs Generic: This is a genuine Carrier/Totaline OEM capacitor, built to exact factory tolerances and tested to 60,000 service hours. Generic capacitors often carry wider MFD tolerances, which can accelerate motor wear and shorten component life over time.
• Install difficulty: 2/5 — Always shut off power at the disconnect and allow several minutes for the capacitor to fully discharge before touching terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to verify discharge). Photograph all wiring connections before removal and reinstall wires on the exact same terminals.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for Carrier model PY3PNA024060NA. Also replaces OEM cross-reference part numbers HC90AA004, HC91CA004, HC90AB004, and 97F5704. Always verify the MFD rating and voltage on your unit's data plate before ordering — if you need help confirming fitment, our team verifies compatibility before you buy.
