OEM Carrier Start Capacitor 175-216 MFD 330V for Model PH12NA048000ACAA

This is the genuine OEM start capacitor (part number P281-1766) factory-specified for the Carrier PH12NA048000ACAA heat pump system. The start capacitor delivers the high-voltage boost required to spin the compressor motor from a dead stop. When this component fails, the compressor typically hums for several seconds and then trips on thermal overload — or refuses to start entirely — leaving your system blowing warm air or shutting down on a hot day.

• Specs: 175–216 MFD (microfarad) | 330V AC rated | Round case | Factory-matched capacitance tolerance for reliable compressor starting
• OEM vs Generic: This genuine Carrier OEM capacitor is manufactured to exact factory specifications. Generic aftermarket capacitors often carry wide MFD tolerances that stress the compressor windings, shortening equipment life and potentially voiding your equipment warranty.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. If uncertain, consult a licensed HVAC technician.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH12NA048000ACAA heat pump (4-ton, R-410A). Always verify the MFD range and voltage rating printed on your existing capacitor's label before ordering — specifications must match exactly for safe operation. Have questions about fitment?
