OEM Carrier Start Capacitor P281-1766 for Model PH15NA03000GBAAA

This is the factory OEM start capacitor (part number P281-1766) specified for the Carrier PH15NA03000GBAAA heat pump. The start capacitor delivers the high-torque electrical boost the compressor motor needs to overcome inertia and reach operating speed. When this capacitor weakens or fails, you'll typically notice hard-start attempts with a loud hum, the compressor tripping on thermal overload, or a complete no-start condition — leaving you with no cooling or heating and a system that may short-cycle or trip the breaker.

• Specs: OEM-matched capacitance (µF) and voltage rating | Factory-specified terminal configuration | Designed to meet original equipment tolerances for the PH15NA03000GBAAA platform
• OEM vs Generic: This is a genuine OEM Carrier part. Generic start capacitors frequently carry ±10–20% capacitance tolerance, which can place excessive stress on the compressor motor windings over time and void compressor warranties. OEM ensures exact-spec performance.
• Install difficulty: 2/5 — Always disconnect power and discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph existing wiring before removal.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Verified fit for Carrier model PH15NA03000GBAAA. Always confirm the capacitance (µF) and voltage rating on your unit's data plate or existing capacitor before ordering to ensure a proper match. Need help verifying fitment?
