OEM Carrier Start Capacitor 175-216 MFD 330V for Model PH12NA04800GACAA

This is the genuine OEM start capacitor (part number P281-1766) factory-specified for the Carrier PH12NA04800GACAA heat pump / air conditioner system. The start capacitor delivers the brief, high-energy electrical surge needed to kick the compressor motor into motion at startup. Without a properly functioning start capacitor, the compressor will attempt to start, draw locked-rotor current, then trip on thermal overload — leaving your system completely unable to cool or heat. A failed start capacitor often presents as a humming unit with no compressor operation, repeated tripped breakers, or a system that runs only intermittently before shutting down.

• Specs: 175–216 MFD (microfarad) | 330VAC rated | Round case form factor | Factory-matched capacitance range for precise motor start performance
• OEM vs Generic: This is a genuine Carrier OEM part sourced directly from the factory supply chain. Generic start capacitors frequently fall outside acceptable MFD tolerance, causing hard starts, compressor wear, and premature failure. OEM ensures the exact capacitance window your compressor motor requires.
• Install Difficulty: 2/5 — Always disconnect and lock out power before servicing. Discharge the capacitor fully before touching terminals — start capacitors hold dangerous charge even after power is removed. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, insulated discharge resistor or resistor-equipped discharge tool, multimeter. Photograph all wiring connections before removal.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Designed as the factory replacement for Carrier model PH12NA04800GACAA. Always verify the MFD rating and voltage printed on your existing capacitor's label before ordering to confirm fitment.
