OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY2PPB060090AB

This OEM single run capacitor is the factory-specified replacement for the Carrier PY2PPB060090AB packaged unit. The run capacitor maintains a continuous phase-shifted current to keep the fan motor or compressor running efficiently after startup. When this capacitor degrades or fails, you'll notice symptoms such as a humming motor that won't spin, intermittent shutdowns, or a system that trips on thermal overload shortly after starting. Replacing it promptly prevents secondary damage to the motor windings.

• Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case | 50/60 Hz | Factory-matched ±5% tolerance — covers OEM part numbers P291-0403, P291-1003, and P291-2503
• OEM vs Generic: This is a genuine OEM Totaline/Carrier capacitor built with high-grade metallized polypropylene film (5–12 microns thick), UL approved, RoHS compliant, and tested to 60,000 service hours. Generic alternatives often use inferior dielectric film, leading to early failure and potential motor damage.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling — it can retain a lethal charge even when power is off. Tools needed: insulated screwdriver, needle-nose pliers, multimeter with capacitance mode. Photograph all wire connections before removal. Match the MFD and voltage ratings exactly to your data plate.
• Warranty: 1-year OEM manufacturer warranty. In stock — ships same business day from our warehouse.
