OEM Carrier Start Capacitor 175–216 MFD 330V for Model PH15NA042000BAAA

This is the genuine OEM replacement start capacitor (part number P281-1766) for the Carrier PH15NA042000BAAA heat pump. The start capacitor provides the high-torque electrical boost the compressor motor needs to overcome inertia at startup. Without a functioning start capacitor, the compressor will hum, trip on thermal overload, or fail to start entirely — leaving you with no cooling or heating. If your system short-cycles immediately after startup or you hear a low hum followed by a click from the contactor, a failed start capacitor is one of the most common culprits.

• Specs: 175–216 MFD (microfarad) | 330V AC rated | Round case form factor | Factory-matched capacitance range per OEM specification
• OEM vs Generic: This is a genuine Carrier OEM part, sourced to exact factory tolerances. Generic start capacitors often carry a wide ±10% MFD variance, which can increase compressor wear and shorten system life — especially critical in a high-efficiency heat pump platform like the PH15NA series.
• Install difficulty: 3/5 — Always disconnect power and discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before removal. The start capacitor is typically mounted in the electrical compartment of the condensing unit.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders ship same business day from our stocked warehouse.

Compatibility: Engineered as the factory-specified replacement for the Carrier PH15NA042000BAAA heat pump. Always verify the MFD range and voltage rating on your unit's data plate or existing capacitor before ordering.
