OEM Carrier Start Capacitor P281-1766 for Model PH3ANA042000BAAA

This is the factory OEM start capacitor for the Carrier PH3ANA042000BAAA heat pump system. The start capacitor provides the high-torque electrical boost the compressor motor needs during startup. Without a functioning start capacitor, the compressor will struggle to start, draw excessive amperage, hum loudly without turning over, or trip the breaker — often within seconds of a call for cooling or heating.

• Specs: OEM Part Number P281-1766 | Factory-rated capacitance and voltage matched to Carrier PH3ANA042000BAAA specifications | ±5% factory tolerance for reliable, consistent motor performance
• OEM vs Generic: This is a genuine OEM Carrier start capacitor built to exact factory specifications. Generic alternatives often carry looser MFD tolerances (±10–20%), which can cause repeated hard-start failures, premature compressor wear, and voided equipment warranties.
• Install Difficulty: 3/5 — Capacitors store a lethal charge even after power is disconnected. Always discharge the capacitor using an insulated resistor or discharge tool before handling. Tools needed: insulated screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal.
• Warranty: 1-year OEM factory warranty on this part. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed specifically for the Carrier PH3ANA042000BAAA heat pump unit.
