OEM Carrier Single Run Capacitor 40 MFD 370V for Model PY3PEA036060NA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY3PEA036060NA packaged heat pump unit. The run capacitor provides the sustained phase-shifted current that keeps the compressor or condenser fan motor spinning at rated efficiency. When this capacitor degrades or fails, you'll typically experience a humming sound with no motor start, intermittent short-cycling, or a complete no-cooling/no-heating condition. Because the PY3PEA036060NA uses separate single run capacitors for the compressor and fan motor circuits, identifying the correct MFD rating on your unit's data plate before ordering is essential.

• Specs: 40 MFD (microfarad) | 370V AC rated | Round case | Factory-matched ±5% tolerance | OEM part numbers P291-0403 and P291-1503
• OEM vs Generic: Genuine Carrier OEM capacitors are manufactured to exact factory tolerances, ensuring proper motor starting torque and run efficiency. Generic capacitors often carry wider ±10% MFD tolerances that accelerate motor winding wear and can void equipment warranties.
• Install Difficulty: 2/5 — Always disconnect power and discharge the capacitor before handling. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections before removal. Typical replacement time: 15–20 minutes.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before 3 PM local time ship same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PEA036060NA 3-ton packaged heat pump unit. Verify the MFD and voltage rating stamped on your existing capacitor or listed on the unit's data plate before ordering — this model uses two separate single run capacitors (compressor and fan motor). Our parts specialists are available to confirm fitment before you purchase.
