OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY2PNB060130AA

This OEM Carrier single run capacitor (part number P291-0403, also cross-referenced as P291-2503) is the factory-specified replacement for the Carrier PY2PNB060130AA packaged heat pump system. As a run capacitor, this component remains energized throughout the entire operating cycle of the motor — stabilizing voltage, improving efficiency, and reducing wear on the blower or condenser fan motor. When this capacitor begins to fail, symptoms include a motor that hums but won't spin, intermittent short-cycling, reduced cooling or heating output, or a motor that runs hot and trips its internal overload. Replacing it promptly prevents downstream compressor and motor damage.

• Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case | ±5% capacitance tolerance | 50/60 Hz | Replaces OEM P/N 97F5704, HC90AA004, HC91CA004, HC90AB004
• OEM vs Generic: This genuine Carrier/Totaline capacitor is reliability-tested to 60,000 service hours per United Technologies application parameters. Generic alternatives often carry ±10% tolerance, accelerating motor stress and shortening service life — especially in a high-cycle packaged heat pump application like the PY2PNB060130AA.
• Install difficulty: 2/5 — Always shut off power at the disconnect and allow the capacitor 5+ minutes to self-discharge before handling. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance function. Photograph all wiring terminals before disconnecting. Verify MFD and voltage rating on the data plate before installing.
• Warranty & Shipping: 1-year OEM factory warranty. RoHS compliant. UL approved with pressure-sensitive interrupter. In stock — ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY2PNB060130AA 5-ton packaged heat pump. Also fits other Carrier, Bryant, and Payne models requiring a 4 MFD 370V oval single run capacitor. Always verify the MFD and voltage rating on your unit's capacitor data label before ordering. Our HVAC parts specialists are available to confirm fitment before you buy.
