OEM Carrier Capacitor Kit — Dual Run 10/10 MFD & Single Run 4 MFD 370V for Model PY1RPA120180ABWB

This factory-authorized OEM capacitor kit is the correct replacement for the Carrier PY1RPA120180ABWB packaged unit. The kit covers three associated OEM part numbers: HC30GB230 (Draft Inducer Motor w/ Capacitor), P291-1013 (Dual Run Capacitor, 10/10 MFD 370V Oval), and P291-0403 (Single Run Capacitor, 4 MFD 370V Oval). Capacitors store and release the electrical charge needed to start and sustain motor operation — including the compressor, condenser fan, and draft inducer. When a capacitor fails, symptoms typically include a persistent hum with no motor start, the unit short-cycling, or a draft inducer lockout fault code triggered during the ignition sequence.

• Specs: P291-1013 — Dual Run, Oval, 10/10 MFD, 370 VAC, 50/60 Hz | P291-0403 — Single Run, Oval, 4 MFD, 370 VAC | HC30GB230 — Draft Inducer Motor Capacitor, 4 MFD 370 VAC | All rated for permanent split-capacitor (PSC) motor applications
• OEM vs Generic: Genuine Carrier/Totaline capacitors are reliability-tested to 60,000 service hours with high-grade metallized polypropylene film and a UL-approved pressure-sensitive interrupter. Generic capacitors typically run ±10% MFD tolerance, accelerating motor wear and increasing the risk of premature compressor failure.
• Install difficulty: 2/5 — Shut off power and allow 5+ minutes for capacitor discharge before touching terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Always photograph wiring before disconnecting. Dual run cap terminals are labeled C (common), HERM (compressor), and FAN — ensure each wire returns to its correct terminal.
• Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse.

Compatibility: Engineered for Carrier model PY1RPA120180ABWB. Verify MFD rating, voltage, and capacitor style against your unit's data plate and wiring diagram before ordering.
