OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY1PEB060115AAAA

This is the factory-specified OEM single run capacitor for the Carrier PY1PEB060115AAAA packaged unit. The run capacitor remains continuously in the circuit whenever the fan motor is operating, providing the phase-shifted electrical charge needed to keep the motor running efficiently. When this capacitor degrades or fails, the fan motor will typically hum but fail to start, short-cycle, draw excess current, or overheat — all signs that immediate replacement is needed to prevent cascading compressor damage.

• Specs: 4 MFD (microfarad) | 370 VAC | Oval case | OEM Totaline/Carrier part | ±5% capacitance tolerance | UL approved | RoHS compliant | Tested to 60,000 service hours
• OEM vs Generic: This is a genuine Carrier (Totaline) OEM capacitor — factory-matched to exact MFD and voltage tolerances. Generic capacitors can run ±10% MFD, accelerating motor winding stress and reducing compressor life over time.
• Install difficulty: 2/5 — Always disconnect power and allow the capacitor to fully discharge before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring before disconnecting. Note: a 440V-rated replacement is an acceptable voltage upgrade if a 370V unit is unavailable.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Fits Carrier model PY1PEB060115AAAA. OEM part numbers covered by this listing: P291-0403 (4 MFD 370V), P291-1003 (10 MFD 370V), and P291-1503 (15 MFD 370V) — all oval single run capacitors at 370V. Verify the MFD and voltage rating on your unit's data plate or existing capacitor label before ordering. Not sure which MFD you need?
