OEM Carrier Dual Run Capacitor 40+5 MFD 370V for Model PY1PNA036080ACBA

This OEM dual run capacitor (Carrier part numbers P291-4053 and cross-reference HC30GB230) is the factory-specified replacement for the Carrier PY1PNA036080ACBA 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 from a single oval-style housing. A failed capacitor is one of the most common causes of A/C no-start conditions — symptoms include a humming compressor that won't turn over, a fan blade that spins only when manually pushed, or a unit that trips the breaker within seconds of startup.

• Specs: 40+5 MFD (microfarad) | 370V rated | Oval case | ±6% tolerance | 50/60 Hz | Castor oil protected | AFC 10,000 | Dimensions: 3⅝" H × 3½" L × 1⅞" W
• OEM vs Generic: This is a genuine Carrier OEM capacitor built to factory ±6% MFD tolerance. Generic aftermarket capacitors are often rated at ±10% or wider, which stresses motor windings, shortens compressor life, and can void equipment warranties. OEM is always the safer long-term investment.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling (use a 20kΩ resistor or insulated screwdriver across terminals). Tools needed: ¼" nut driver, needle-nose pliers, multimeter with capacitance mode. Photograph all wire connections before disconnecting. Terminal labels: HERM (compressor), FAN (condenser fan motor), COM (common).
• Warranty & Shipping: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse. Note: P291-4053 has been superseded by P291-4054 / P291-4054RS — all are direct drop-in replacements with identical ratings.
