OEM Carrier Start Capacitor 175-216 MFD 330V for Model PH4ANG042000BBAA

This genuine OEM start capacitor (part number P281-1766) is the factory-specified replacement for the Carrier PH4ANG042000BBAA heat pump system. The start capacitor delivers a powerful burst of electrical energy to kick-start the compressor motor during each cooling or heating cycle. Without a functioning start capacitor, the compressor will struggle to turn over, hum without starting, or trip the breaker entirely — leaving your system locked out and unable to condition the space.

• Specs: 175–216 MFD (microfarad) range | 330V AC rated | Round case | Factory OEM tolerance — exact match to data plate specifications for PH4ANG042000BBAA
• OEM vs Generic: This is a genuine Carrier OEM capacitor sourced directly from the factory supply chain. Generic start capacitors often fall outside the rated MFD window, causing repeated hard-start stress on the compressor and premature failure of the run windings.
• Install Difficulty: 2/5 — Always disconnect power and discharge the capacitor fully before handling. Tools needed: flathead or Phillips screwdriver, needle-nose pliers, multimeter (to verify discharge and confirm MFD rating). Photograph all wiring connections before removal.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our stocked warehouse — no waiting on back-orders.

Compatibility: Designed for the Carrier PH4ANG042000BBAA heat pump. Always verify the MFD range and voltage rating on your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists confirm fitment before you check out — call or chat today.
