OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY1PEB048130ABAA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY1PEB048130ABAA packaged unit. The run capacitor remains in the circuit the entire time the fan motor or compressor is operating, providing the phase-shifted current needed to keep the motor running efficiently. When a run capacitor fails, symptoms include a loud humming with no motor movement, the unit starting then shutting off within seconds, or reduced cooling output due to a struggling motor drawing excess amperage.

• Specs: 4 MFD (microfarad) | 370 VAC | Oval case | Single run | 50/60 Hz | Replaces OEM part numbers P291-0403, P291-1003, and P291-1503
• OEM vs Generic: This is a genuine Carrier/Totaline OEM capacitor manufactured to exact factory tolerance. Generic capacitors often carry a ±10% MFD variance, accelerating motor wear, increasing energy draw, and shortening compressor life — the OEM unit is the only risk-free replacement.
• Install difficulty: 2/5 — Always shut off power at the disconnect and wait 5 minutes for the capacitor to self-discharge before handling. Tools needed: flathead screwdriver, needle-nose pliers, multimeter with capacitance setting. Photograph all wiring connections before removal.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
