OEM Carrier Dual Run Capacitor P291-4553RS for Model PY3PNA030060NA

This OEM dual run capacitor (P291-4553RS) is the factory-specified replacement for the Carrier PY3PNA030060NA split-system air conditioner. The dual run capacitor stores and releases the electrical charge required to start and sustain both the compressor and the condenser fan motor simultaneously. When this capacitor degrades or fails, the most common symptoms include a loud hum with no motor movement, the system tripping on high-pressure lockout, or the condenser fan spinning weakly and causing the unit to overheat and short-cycle within minutes.

• OEM Part Numbers: Primary — P291-4553RS (Dual Run Capacitor) | Supplemental — P291-0403 (Single Run Capacitor) & P291-1503 (Single Run Capacitor) — all factory-matched to the PY3PNA030060NA unit specifications.
• OEM vs Generic: OEM capacitors are manufactured to exact factory MFD tolerance (±3%), ensuring proper motor start torque and compressor longevity. Generic aftermarket capacitors commonly run ±10% tolerance, accelerating wear on the compressor windings and shortening overall equipment life.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before touching any terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Turn off power at the disconnect and breaker before beginning.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse when ordered before 3 PM EST.

Compatibility: Engineered specifically for the Carrier PY3PNA030060NA condensing unit. Always verify the MFD rating and voltage printed on your existing capacitor's data label before ordering — this ensures a perfect drop-in fit with no wiring modifications required. Not sure it fits?
