OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY1PEB048130NBAA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY1PEB048130NBAA packaged unit. The run capacitor remains in the circuit continuously during motor operation, stabilizing voltage and ensuring the fan motor runs efficiently. When it degrades or fails, you'll typically notice a humming sound with no motor movement, the unit blowing warm air, short cycling, or the system failing to start altogether. Visible swelling or oil residue on the capacitor body is also a clear sign of failure.

• Specs: 4 MFD (microfarad) | 370 VAC | Oval case | 50/60 Hz | OEM part numbers: P291-0403 (4 MFD 370V), P291-1003 (10 MFD 370V), P291-1503 (15 MFD 370V) — select the MFD rating that matches your unit's data plate
• OEM vs Generic: This is a genuine Totaline/Carrier OEM capacitor tested to 60,000 service hours with 100% electrical testing at the factory and UL-approved pressure-sensitive interrupter for safe failure. Generic aftermarket units often carry ±10% MFD tolerance versus OEM precision, accelerating motor wear over time.
• Install difficulty: 2/5 — Shut off power at the disconnect box and wait 5 minutes for residual charge to bleed before touching any terminals. Tools needed: flathead or 1/4" nut driver, needle-nose pliers, multimeter (to verify discharge). Always photograph existing wiring before disconnecting terminals. Match the MFD and voltage rating exactly to the data plate.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
