OEM Carrier Start Capacitor P281-1766 for Model PH15NA02400GBAAA

This is the genuine OEM start capacitor for the Carrier PH15NA02400GBAAA heat pump. The start capacitor provides the high-torque electrical boost the compressor needs to overcome initial inertia and reach full operating speed. Without a functioning start capacitor, the compressor draws excessive locked-rotor amperage, trips the breaker, or simply hums and fails to start. Replacing a failed start capacitor promptly protects your compressor — one of the most expensive components in any system.

• Specs: OEM part number P281-1766 | Factory-matched capacitance and voltage rating | Designed for single-phase compressor hard-start duty on the Carrier PH15NA02400GBAAA
• OEM vs Generic: This is the genuine Carrier-specified start capacitor. OEM components meet exact factory capacitance tolerances, ensuring reliable start-up torque and maximum compressor lifespan. Generic alternatives often deviate in capacitance or voltage ratings, risking premature compressor failure.
• Install Difficulty: 2/5 — Always disconnect and lock out power before beginning. Discharge any residual voltage from the old capacitor using a resistor or insulated discharge tool before touching terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Capacitor replacement is typically a 20–30 minute job for a qualified technician.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse — get your system back up and running fast.

Compatibility: Engineered as the factory-direct replacement for the Carrier PH15NA02400GBAAA heat pump. Always verify the capacitance (MFD) and voltage rating on your existing capacitor's label or your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists are available to confirm fitment before you buy — no guesswork required.
