OEM Carrier Dual Run Capacitor 35+5 MFD 370V for Model PY1PNA030040ACBA

This OEM dual run capacitor is the factory-specified replacement for the Carrier PY1PNA030040ACBA packaged unit. Referenced under OEM part numbers P291-3553 and HC30GB230, this capacitor stores and releases the electrical charge required to start and sustain both the compressor and condenser fan motor during every cooling cycle. A failed capacitor typically presents as a humming outdoor unit with no motor movement, short-cycling within minutes of startup, or the system running but blowing warm air—all signs that the capacitor can no longer hold its rated charge.

• Specs: 35+5 MFD (microfarad) | 370 VAC rated | Oval case | Factory-matched ±5% tolerance | 50/60 Hz | Terminals labeled HERM – C – FAN
• OEM vs Generic: This OEM capacitor meets Carrier's exact factory tolerance specifications. Generic aftermarket units frequently run outside the ±5% MFD window, placing added stress on the compressor windings and shortening overall system life.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before touching any terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance function. Photograph all wiring connections before disconnecting the old capacitor.
• Warranty: 1-year OEM factory warranty included. Orders placed before our same-business-day cutoff ship from our warehouse today.

Compatibility: Fits Carrier model PY1PNA030040ACBA packaged unit. Always verify the MFD rating and voltage on your unit's data plate before ordering — using an incorrect MFD value can damage the compressor or fan motor. Our fitment team is available to confirm compatibility before you place your order.
