OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY2PPB060115AB

This is the genuine OEM Carrier single run capacitor factory-specified for the Carrier PY2PPB060115AB packaged unit. Unlike a dual run capacitor, the single run capacitor remains in the circuit continuously throughout motor operation, stabilizing voltage and ensuring efficient, reliable motor performance. When this capacitor fails, you'll typically experience a humming or buzzing sound with no motor movement, a fan or blower that fails to start, or a unit that short-cycles and shuts off shortly after attempting to start. Prompt replacement prevents secondary motor damage caused by locked-rotor current draw.

• Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case | ±5% capacitance tolerance | 50/60 Hz | Replaces OEM part numbers P291-0403, P291-1003, and P291-2503
• OEM vs Generic: This is a genuine Carrier Totaline-branded OEM capacitor manufactured to factory tolerance specifications, built with high-grade metallized polypropylene film and 100% electrically tested before shipment. Generic alternatives often ship with ±10% MFD tolerance, which accelerates motor wear and can void equipment warranties.
• Install difficulty: 2/5 — Always shut off power at the disconnect and allow 5 minutes for residual charge to dissipate before touching terminals. Tools needed: flathead and Phillips screwdriver, needle-nose pliers, multimeter (for verification). Photograph all wiring connections before disconnecting the old capacitor.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse — order before 3 PM local time for guaranteed same-day dispatch.

Compatibility: Engineered for the Carrier PY2PPB060115AB packaged unit. Always cross-reference the MFD and voltage rating on your unit's data plate before ordering — voltage rating must match or be higher (e.g., a 440V-rated capacitor is acceptable in a 370V application). This part also cross-references OEM numbers P291-1003 and P291-2503. Questions about fitment? Our HVAC parts specialists verify compatibility before you buy.
