OEM Carrier Start Capacitor P281-1766 for Model PH4ANG030000BDAA

This is the factory OEM start capacitor (part number P281-1766) designed specifically for the Carrier PH4ANG030000BDAA heat pump system. The start capacitor delivers the high-torque electrical boost the compressor motor needs to overcome inertia and reach operating speed. When this component fails, you'll typically experience symptoms such as a humming compressor that won't turn over, hard-start trips on the breaker, or a complete no-start condition — leaving your system unable to heat or cool.

• Specs: OEM-matched capacitance (MFD) and voltage rating | Factory-specified for Carrier PH4ANG030000BDAA | Round or oval case per OEM design | ±5% tolerance for reliable motor engagement
• OEM vs Generic: This is a genuine OEM part (P281-1766), manufactured to Carrier's exact electrical specifications. Generic aftermarket start capacitors often carry wider tolerance ranges (±10–20%), which can cause repeated hard-start stress on your compressor and void equipment warranties.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling. Tools needed: insulated screwdriver, 1/4" nut driver, needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections before removal.
• Warranty: Backed by a 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for the Carrier PH4ANG030000BDAA heat pump. Always confirm the capacitance (MFD) and voltage rating printed on your existing capacitor's label matches this part before installation. Not sure it fits?
