OEM Carrier Start Capacitor 175-216 MFD 330V for Model PH3ANA018000BAAA

This genuine OEM start capacitor (part number P281-1766) is the factory-specified replacement for the Carrier PH3ANA018000BAAA. The start capacitor delivers the high-voltage surge of energy needed to energize the compressor motor at startup. Without a functioning start capacitor, the compressor will attempt to start, draw excessive amperage, and either trip the breaker or fail to run entirely — leaving you with no cooling. If your system is humming but not starting, or is tripping the breaker on startup, this component is the most likely culprit.

• Specs: 175–216 MFD (microfarad) | 330V AC rated | Round case form factor | Factory-matched Carrier OEM specification (P281-1766)
• OEM vs Generic: This is a genuine Carrier-sourced OEM start capacitor. Generic alternatives often carry wider MFD tolerances, which can stress the compressor motor windings and shorten equipment life. OEM ensures exact-spec performance every time.
• Install difficulty: 2/5 — Always disconnect power and discharge the capacitor fully before handling. Tools needed: flathead and Phillips screwdriver, needle-nose pliers, multimeter. Photograph all wiring connections before removal to ensure correct reinstallation.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
