OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY3PEA048130NA

This is the factory-specified OEM single run capacitor for the Carrier PY3PEA048130NA packaged unit. Run capacitors store and continuously release the electrical charge needed to keep the condenser fan motor or blower motor running at peak efficiency. When this capacitor weakens or fails, the motor it supports will struggle to start, run hot, draw excess amperage, or fail to run entirely — often leaving your system blowing warm air or shutting down on thermal overload.

This listing covers both OEM part numbers used on this unit: P291-0403 (4 MFD 370V) and P291-1503 (15 MFD 370V). Verify the MFD rating printed on your existing capacitor before selecting. Mixing MFD ratings will damage motors — always match exactly.

• Specs: Single run capacitor | Oval case | 370 VAC rated | Available in 4 MFD (P291-0403) and 15 MFD (P291-1503) | ±5% capacitance tolerance | 50/60 Hz
• OEM vs Generic: These are genuine Carrier/Totaline OEM capacitors, tested to 60,000 service hours with 100% electrical testing at the factory. Generic capacitors often run at ±10% tolerance, accelerating motor bearing wear and shortening equipment life.
• Install Difficulty: 1/5 — One of the simplest HVAC repairs. Discharge the capacitor fully before touching terminals (use a 20,000-ohm resistor or insulated screwdriver across terminals). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Always photograph terminal wiring before disconnecting.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Fits Carrier model PY3PEA048130NA packaged units. Always verify the MFD rating and voltage on your existing capacitor's data label before ordering — do not substitute a different MFD value. Questions about fitment?
