OEM Carrier Dual Run Capacitor 10/10 MFD 370V & Single Run Capacitor 4 MFD 370V for Model PY1RPA150224ADWB

This OEM Carrier capacitor kit covers both the dual run capacitor (P291-1013 / successor P291-1014) and the single run capacitor (P291-0403 / successor P291-0404) — the two factory-specified capacitors for the Carrier PY1RPA150224ADWB packaged unit. The dual run capacitor simultaneously supports both the compressor and condenser fan motor, while the single run capacitor sustains the blower or auxiliary motor during normal operation. A failing capacitor typically presents as a humming unit that won't start, a compressor that kicks off after a few seconds, or a fan blade that spins slowly or only when manually spun. These are among the most common HVAC service calls — and one of the most cost-effective repairs you can make.

• Dual Run Capacitor Specs (P291-1013 / P291-1014): 10+10 MFD (microfarad) | 370 VAC | Oval case | Aluminum housing | 50/60 Hz | Factory-matched ±3% tolerance | Replaces HC93CA013, GE Genteq 27L180
• Single Run Capacitor Specs (P291-0403 / P291-0404): 4 MFD | 370 VAC | Oval case | Aluminum housing | 50/60 Hz | UL Approved with pressure-sensitive interrupter | Replaces HC90AA004, HC91CA004, HC90AB004
• OEM vs Generic: Carrier Totaline OEM capacitors are tested to 60,000 service hours and built with high-grade metallized polypropylene film (5–12 microns thick). Generic capacitors often run ±10% MFD tolerance, which accelerates motor wear, stresses the compressor, and shortens overall system life — especially under heavy seasonal loads.
• Install difficulty: 2/5 — Always discharge capacitors before touching terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance function. Photograph all wiring before disconnecting. Match MFD and voltage ratings exactly from your unit's data plate before installing.
• Warranty & Shipping: 1-year OEM factory warranty. RoHS compliant. Ships same business day from our warehouse when ordered by 3PM local time.

Compatibility: Both capacitors are factory-specified replacements for the Carrier PY1RPA150224ADWB packaged unit. Note: P291-1013 has been superseded by P291-1014, and P291-0403 has been superseded by P291-0404 — all are cross-compatible. Always verify MFD and voltage ratings on your unit's data plate before ordering. Have questions about fitment?
