OEM Carrier Dual Run Capacitor 35+5 MFD 370V for Model PY1PNA024040ACBA

This OEM dual run capacitor is the factory-specified replacement for the Carrier PY1PNA024040ACBA packaged unit, cross-referenced under OEM part numbers P291-3553 and HC30GB230. The dual run capacitor stores and releases the precise electrical charge needed to start and sustain both the compressor and the condenser fan motor during every cooling cycle. When the capacitor begins to fail, you'll typically notice the system humming without the compressor or fan spinning up, warm air coming from the supply vents, or the unit short-cycling and tripping on thermal overload. Left unaddressed, a weak capacitor accelerates wear on the compressor windings — one of the most expensive components in any packaged unit.

• Specs: 35+5 MFD (microfarad) | 370 VAC rated | Oval case | Three terminals labeled HERM – C – FAN | Factory-matched ±3% tolerance | 50/60 Hz
• OEM vs Generic: This is a genuine Carrier OEM capacitor built to exact factory tolerances. Generic aftermarket units often carry a ±10% MFD variance, which over-stresses compressor start windings and shortens equipment life — especially in packaged rooftop configurations with limited airflow.
• Install difficulty: 2/5 — Always discharge the capacitor before touching any terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance mode. Photograph or label all wire connections before removal. Verify MFD and voltage ratings match your unit's data plate before installing.
• Warranty & Shipping: 1-year OEM factory warranty. In stock and ships same business day from our warehouse — order by 3 PM local time for next-day arrival in most regions.

Compatibility: Fits Carrier model PY1PNA024040ACBA packaged unit. Cross-references: P291-3553, P291-3553RS, P291-3554 (current OEM successor), and HC30GB230 capacitor assembly. Always confirm the MFD rating and voltage on your unit's data plate before ordering. Have a question about fitment?
