OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY2PPB060090NB

This OEM single run capacitor is the factory-specified replacement for the Carrier PY2PPB060090NB and is used to maintain a continuous phase-shifted current to the motor winding, keeping the motor running efficiently after startup. When this capacitor fails, the motor it supports loses its run winding assistance — symptoms include a humming motor that won't spin, intermittent short-cycling, or a unit that trips on thermal overload within minutes of starting. Replacing it promptly prevents downstream motor damage and compressor strain.

• Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case | Factory-matched ±5% tolerance | OEM Part Numbers: P291-0403, P291-1003, P291-2503 | Replaces: HC90AA004, HC91CA004, HC90AB004
• OEM vs Generic: This Carrier Totaline OEM capacitor is proven to 60,000 service hours and is subjected to 100% electrical testing at the factory. Generic capacitors often run wider MFD tolerances, increasing motor heat and shortening run life.
• Install difficulty: 1/5 — One of the easiest HVAC repairs. Discharge the capacitor before touching terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Always photograph existing wiring before disconnecting terminals.
• Warranty: 1-year OEM factory warranty. UL Approved with patented pressure-sensitive interrupter. RoHS compliant. Ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY2PPB060090NB.
