OEM Carrier Dual Run Capacitor P291-7053RS for Model PY3GNA048090AA

This OEM dual run capacitor (part number P291-7053RS) is the factory-specified replacement for the Carrier PY3GNA048090AA packaged unit. The dual run capacitor stores and releases the electrical charge needed to start and sustain both the compressor and the condenser fan motor simultaneously. When this capacitor begins to fail, you'll typically notice symptoms such as a humming condenser with no motor movement, a fan that spins only when manually nudged, or a system that short-cycles and trips on thermal overload. Left unaddressed, a weak or failed capacitor will accelerate compressor wear and can lead to costly system damage.

• Part Specs: OEM part number P291-7053RS | Dual run configuration (compressor + fan) | Factory-matched MFD rating and 370V/440V voltage | Round capacitor case with industry-standard quick-connect terminals
• OEM vs. Generic: This is a genuine OEM Carrier capacitor built to exact factory tolerance (±3% MFD). Aftermarket generic capacitors commonly carry ±10% tolerance, which accelerates motor and compressor wear over time and may void equipment warranties.
• Install Difficulty: 2/5 — Capacitors store a lethal charge even after power is off. Always discharge the capacitor using an insulated resistor tool before handling. Tools required: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting the old unit.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In-stock units ship same business day from our NationalHVACParts.com warehouse when ordered before 3 PM EST.

Compatibility: Engineered as a direct OEM replacement for the Carrier PY3GNA048090AA packaged unit (4-ton, 90,000 BTU gas/electric). Always verify the MFD rating and voltage printed on your existing capacitor's label or the unit's data plate before finalizing your order. Need help confirming fitment? Our HVAC parts specialists are available to verify compatibility before you buy — no guesswork required.
