OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY3PEA048130AA

This is the genuine OEM single run capacitor factory-specified for the Carrier PY3PEA048130AA heat pump system. The run capacitor stores and continuously releases electrical energy to keep the condenser fan motor or compressor running at peak efficiency throughout every cycle. When it degrades or fails, you'll typically notice a humming or buzzing sound with no motor movement, the unit blowing warm air, short-cycling, or a complete no-start condition. Replacing this capacitor with the correct OEM part restores factory-spec performance and protects downstream motor components from overload stress.

• Specs: 4 MFD (microfarad) ±5% tolerance | 370 VAC rated | Oval style case | OEM Part Numbers: P291-0403 (primary), P291-1503 (secondary/variant) | Replaces legacy P/N 97F5704
• OEM vs Generic: This factory-original Carrier capacitor is manufactured to exact MFD and voltage tolerances. Generic capacitors often carry a ±10% MFD variance, which accelerates motor winding wear and can shorten compressor life — particularly critical on 4-ton heat pump platforms like the PY3PEA048130AA.
• Install Difficulty: 2/5 — Discharge the capacitor fully before touching terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Always photograph existing wiring connections before removal. Verify MFD and voltage against your unit's data plate before installation.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Designed for Carrier model PY3PEA048130AA. Cross-references OEM part numbers P291-0403 and P291-1503. Always confirm the MFD rating and voltage on your existing capacitor's label before ordering. Our fitment team is available to verify compatibility before you purchase — no guesswork required.
