OEM Carrier Start Capacitor 175-216 MFD 330V for Model PH3ANA018000BBAA

This is the genuine OEM start capacitor (part number P281-1766) factory-specified for the Carrier PH3ANA018000BBAA heat pump system. The start capacitor delivers the high-torque electrical boost the compressor motor needs during startup. Without a functioning start capacitor, the compressor will attempt to start, draw excess amperage, and either trip the breaker or lock out entirely — leaving your system with no cooling or heating. If your unit hums briefly and then shuts off, or fails to start at all, a failed start capacitor is one of the most common culprits.

• Specs: 175–216 MFD (microfarad) | 330V rated | Round case | Factory OEM tolerance — direct replacement for P281-1766
• OEM vs Generic: This is a genuine Carrier OEM part built to exact factory specifications. Generic start capacitors often fall outside the rated MFD range, causing hard-start conditions that stress the compressor and shorten its lifespan — costing far more in the long run.
• Install difficulty: 2/5 — Always discharge the capacitor before handling. Photograph all wiring connections prior to removal. Tools needed: insulated screwdrivers, 1/4" nut driver, needle-nose pliers, and a multimeter to confirm the old capacitor has failed before replacing.
• Warranty: Backed by a 1-year OEM manufacturer warranty. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for the Carrier PH3ANA018000BBAA. Note that Carrier sources capacitors from third-party manufacturers — the label on the capacitor may reflect the component manufacturer rather than Carrier. Always verify the MFD range and voltage rating on your unit's data plate before ordering. Have a fitment question? Our HVAC parts specialists confirm compatibility before you buy.
