OEM Carrier Start Capacitor P281-8806 for Model PH13NR01800GAHAA

This is the OEM-specified start capacitor for the Carrier PH13NR01800GAHAA heat pump / split-system unit. The start capacitor provides the high-torque electrical boost the compressor motor needs during startup. Without a properly functioning start capacitor, the compressor struggles to turn over — resulting in a hard-start condition, repeated tripping of the overload protector, or a complete no-start failure where the outdoor unit hums but never runs. Replacing a failed start capacitor is one of the most cost-effective repairs in HVAC service.

• Part Number: P281-8806 | OEM Carrier factory replacement | Exact-match capacitance and voltage rating for the PH13NR01800GAHAA platform
• OEM vs Generic: OEM start capacitors are manufactured to strict factory tolerances, ensuring reliable compressor startups and protecting motor windings from damaging voltage spikes. Generic alternatives often carry wider tolerance bands that can shorten compressor life.
• Install Difficulty: 2/5 — Always disconnect and lock out power at the disconnect box before beginning work. Capacitors retain a lethal charge even after power is removed — discharge fully before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter with capacitance mode. Photograph all wiring before disconnecting terminals.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for Carrier model PH13NR01800GAHAA. Always cross-reference the capacitance (MFD) and voltage rating printed on your original capacitor's label or unit data plate before ordering to confirm fitment. Not sure?
