OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY1RPA072115ACWA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY1RPA072115ACWA packaged unit's draft inducer motor circuit. Cross-referenced under OEM part numbers P291-0403, P291-1003, and assembly reference HC30GB230, this oval 4 MFD 370V capacitor provides the phase-shift energy required to start and sustain the inducer motor that exhausts combustion gases. When the capacitor weakens or fails, the inducer motor will hum without spinning, trip the pressure switch, and lock out the furnace section before ignition — leaving you with no heat.

• Specs: 4 MFD (microfarad) | 370V AC rated | Oval case | Factory-matched ±5% tolerance | 50/60 Hz compatible
• OEM vs Generic: This is the genuine Carrier/Totaline OEM capacitor, tested to 60,000 service hours per United Technologies reliability parameters. Generic alternatives often run wider MFD tolerances, increasing inducer motor stress and shortening service life.
• Install difficulty: 2/5 — Always discharge the capacitor before handling. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance function. Photograph all wiring before disconnecting terminals. Verify the MFD and voltage rating on the motor nameplate before ordering.
• Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY1RPA072115ACWA packaged unit draft inducer motor circuit. Also cross-references HC30GB230 motor assembly (4 µF 370V capacitor component), P291-0403, and P291-1003. Confirm your unit's capacitor MFD and voltage rating on the motor data plate before ordering.
