OEM Carrier Single Run Capacitor 4 MFD 370V Oval for Model PY2PPB042060NB

This OEM single run capacitor is the factory-specified replacement for the Carrier PY2PPB042060NB packaged unit. Carrying part numbers P291-0403 (4 MFD) and P291-1503 (15 MFD), these oval run capacitors maintain the continuous electrical charge required to keep the condenser fan motor or blower motor running efficiently after startup. When a run capacitor fails, the motor may hum but refuse to spin, overheat and trip on thermal overload, or cause the entire system to short-cycle — leaving you without cooling or heating.

• Specs (P291-0403): 4 MFD (microfarad) | 370 VAC rated | Oval case | 50/60 Hz | Factory-matched ±5% tolerance | Replaces OEM cross-references HC90AA004, HC91CA004, HC90AB004, and GE/Genteq 97F5704
• OEM vs Generic: This is a genuine Carrier/Totaline OEM capacitor built to exact factory tolerances. Generic alternatives often carry wider MFD variance (±10%), which accelerates motor winding stress and shortens component service life — a false economy on a packaged rooftop or split system.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: flathead or Phillips screwdriver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before removal. Match MFD and voltage ratings exactly to your unit's data plate.
• Warranty & Shipping: 1-year OEM factory warranty. In stock and ships same business day from our warehouse — get your system back up and running fast.

Compatibility: Designed for the Carrier PY2PPB042060NB packaged unit. Note: P291-1503 (15 MFD 370V) has been discontinued by Carrier; the current direct replacement is P291-1504 (15 MFD 440V). Always verify the MFD rating and voltage on your unit's original capacitor data label before ordering. Our parts specialists are available to confirm fitment before you buy.
