OEM Carrier Start Capacitor 175-216 MFD 330V for Model PH12NA048000ABAA

This is the genuine OEM replacement start capacitor (part number P281-1766) factory-specified for the Carrier PH12NA048000ABAA heat pump system. The start capacitor delivers a high-energy electrical boost to kick the compressor into motion at startup, then drops out of the circuit once the motor reaches operating speed. When this component fails, the compressor draws locked-rotor amperage without turning — resulting in tripped breakers, a humming condenser with no compressor engagement, or complete system shutdown after a single startup attempt. Replacing it promptly protects the compressor from thermal overload damage.

• Specs: 175–216 MFD (microfarad) | 330V rated | Round case form factor | Venstar/Totaline OEM-sourced to Carrier specification
• OEM vs Generic: This OEM unit is built to exact Carrier factory tolerances. Generic start capacitors frequently fall outside acceptable MFD range, causing hard-start stress on the compressor and shortening its service life. Note: as is standard for Carrier, the capacitor label will reflect the OEM capacitor manufacturer's name (e.g., Venstar/Totaline), not the Carrier brand name.
• Install difficulty: 2/5 — Discharge the capacitor fully before touching terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Always photograph wiring before disconnecting old unit. Ensure power is locked out at the disconnect and breaker before beginning.
• Warranty & Shipping: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse.
