OEM Carrier Start Capacitor P281-1766 for Model PH3ANA024000BAAA

This is the factory OEM start capacitor for the Carrier PH3ANA024000BAAA heat pump or air conditioning system. The start capacitor provides the extra electrical boost needed to get the compressor motor spinning from a dead stop. Without a properly functioning start capacitor, the compressor will draw excessive locked-rotor amperage, hum loudly, trip the breaker, or fail to start entirely — leading to no cooling or heating output. Replacing a failed start capacitor promptly protects your compressor from costly burnout.

• Specs: OEM Part Number P281-1766 | Factory-matched MFD and voltage rating | Engineered to meet Carrier's exact electrical tolerances for the PH3ANA024000BAAA platform
• OEM vs Generic: This is a genuine OEM Carrier part — not an aftermarket substitute. OEM capacitors are manufactured to tight ±3–5% MFD tolerances, ensuring reliable starts and maximum compressor longevity. Generic capacitors can run ±10% or worse, increasing wear on motor windings over time.
• Install Difficulty: 2/5 — Always disconnect power and discharge the capacitor before handling. Tools needed: flathead or Phillips screwdriver, 1/4" nut driver, needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections before removal.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed and factory-specified for the Carrier PH3ANA024000BAAA. Always verify the MFD rating and voltage on your unit's data plate or existing capacitor before ordering to confirm an exact match.
