OEM Carrier Dual Run Capacitor 40+5 MFD 440V for Model PY1PJB048130AAAA

This is the OEM factory-specified dual run capacitor for the Carrier PY1PJB048130AAAA packaged unit. The dual run capacitor stores and delivers the electrical charge required to start and run both the compressor and condenser fan motor simultaneously. When this component fails, you'll typically notice the system humming without starting, the compressor or fan shutting down shortly after startup, or the unit tripping on thermal overload. Replacing a failed capacitor promptly protects your compressor — the most expensive component in the system — from damaging low-voltage run conditions.

• Specs: 40+5 MFD (microfarad) | 370/440V rated | Round case | OEM part numbers: P291-4054 (primary), P291-0403, P291-1503 | Replaces Totaline P291-4054RS
• OEM vs Generic: This OEM capacitor is factory-matched to ±3% MFD tolerance. Generic capacitors commonly drift ±10%, which forces your compressor and fan motor to work harder, accelerating wear and shortening equipment life.
• Install Difficulty: 2/5 — Always discharge the capacitor before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to verify capacitance before and after). Photograph all wire connections before disconnecting the old unit.
• Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered as a direct drop-in replacement for Carrier model PY1PJB048130AAAA packaged units. Note: Carrier sources capacitors from third-party manufacturers — the label on the capacitor body may reflect the capacitor manufacturer's name rather than Carrier, which is normal and expected for OEM parts. Always verify MFD rating, voltage, and terminal configuration against your unit's data plate before ordering. Our team is available to confirm fitment — reach out before you buy.
