OEM Carrier Dual Run Capacitor 10/10 MFD 370V for Model PY1RPA090180ACWA

This OEM dual run capacitor is the factory-specified replacement for the Carrier PY1RPA090180ACWA packaged rooftop unit. Carrier part numbers P291-1013 (dual run) and P291-0403 (single run) are the capacitor references for this unit, with HC30GB230 covering the draft inducer motor assembly that pairs with the capacitor circuit. The dual run capacitor stores and releases the electrical charge needed to start and sustain both the compressor and condenser fan motor simultaneously. When this capacitor degrades or fails, common symptoms include a humming compressor that won't start, the condenser fan spinning slowly or not at all, or the unit short-cycling and tripping on high-pressure lockout within minutes of startup.

• Specs: 10 + 10 MFD (microfarad) | 370V rated | Oval case | 50/60 Hz | Aluminum housing | Factory-matched ±5% tolerance — replaces OEM P/N HC93CA013 and GE Genteq 27L180
• OEM vs Generic: OEM Carrier capacitors are validated to factory tolerance specifications. Off-brand generic capacitors frequently run outside rated MFD tolerance, causing increased motor winding stress, accelerated compressor wear, and shortened equipment life.
• Install difficulty: 2/5 — Discharge the capacitor fully before touching any terminals (use a 20kΩ resistor or insulated discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance setting. Always photograph existing wiring connections before disconnecting terminals — HERM, FAN, and COM labels must be matched exactly.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Fits Carrier model PY1RPA090180ACWA packaged rooftop unit. Cross-references: P291-1013, P291-0403, HC93CA013, GE Genteq 27L180. Always verify the MFD rating and voltage on your unit's capacitor data label before ordering. Not sure it fits? Our HVAC parts specialists verify fitment before you buy — contact us anytime.
