OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY3PPA042060NA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY3PPA042060NA packaged unit. The run capacitor maintains a continuous phase shift in the motor winding to keep the condenser fan motor or blower motor running at full torque and efficiency. When the capacitor weakens or fails, the motor may hum without spinning, draw excessive current, overheat, or fail to start entirely — often causing the entire system to shut down on a thermal overload.

• Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case | ±5% factory tolerance | 50/60 Hz | OEM Part Numbers: P291-0403 / P291-1503
• OEM vs Generic: This is a genuine Carrier/Totaline OEM capacitor, tested to 60,000 service hours with 100% electrical inspection at the factory. Generic capacitors often run at ±10% MFD tolerance, accelerating motor wear and reducing equipment lifespan.
• Install difficulty: 2/5 — Discharge the old capacitor fully before touching any terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Always photograph existing wiring before disconnecting the terminals.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PPA042060NA packaged unit. Always verify the MFD rating and voltage on your unit's data plate before ordering — substituting an incorrect MFD value will damage the motor.
