OEM Carrier Dual Run Capacitor 40+5 MFD 440V for Model PY1PNA042100ADBA

This OEM dual run capacitor is the factory-specified replacement for the Carrier PY1PNA042100ADBA condensing unit. Referenced under inducer motor assembly HC30GB230 and direct capacitor part number P291-4054, this capacitor stores and releases the electrical charge required to start and sustain both the compressor and condenser fan motor simultaneously. When it fails, symptoms typically include a loud hum with no motor movement, the system short-cycling within seconds of startup, or a complete failure to turn on — leaving you without cooling on the hottest days.

• Specs: 40+5 MFD (microfarad) | 440V rated | Oval/Round case | ±6% factory tolerance | 50/60 Hz rated | UL approved with pressure-sensitive interrupter
• OEM vs Generic: This is a genuine Carrier OEM capacitor sourced from the factory-approved manufacturer. OEM units maintain tight ±6% MFD tolerance, protecting your compressor and fan motor from voltage stress. Generic off-brand capacitors often drift beyond ±10%, accelerating motor wear and shortening compressor life significantly.
• 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. Photograph all wiring connections before disconnecting. The swap itself is a straightforward terminal-for-terminal replacement.
• Warranty: 1-year OEM manufacturer warranty. In-stock units ship the same business day from our warehouse — order by 5 PM local time.

Compatibility: Designed for Carrier model PY1PNA042100ADBA condensing units specifying a 40+5 MFD 440V dual run capacitor (P291-4054 / HC30GB230 assembly).
