OEM Carrier Start Capacitor P281-8806 for Model PH14NA01800GAAAA

This OEM start capacitor (part number P281-8806) is the factory-specified replacement for the Carrier PH14NA01800GAAAA heat pump condensing unit. The start capacitor delivers the high-voltage electrical boost required to get the compressor motor spinning from a dead stop. Without a functioning start capacitor, the compressor struggles to start, draws excessive amperage, and trips the breaker — or simply won't turn on at all. If your Carrier heat pump hums briefly and shuts off, repeatedly trips the breaker, or refuses to start on warm days when line voltage sags, a failed start capacitor is one of the most common culprits.

• Specs: OEM-matched microfarad (MFD) and voltage rating | Factory-specified for Carrier PH14NA01800GAAAA | Designed for high-cycle compressor start duty | Exact form-factor for drop-in replacement
• OEM vs Generic: This is a genuine OEM part manufactured to Carrier's exact tolerance specifications. Generic start capacitors often deviate in MFD rating and temperature rating, leading to premature compressor wear, hard-start faults, and shortened equipment life.
• Install Difficulty: 3/5 — Start capacitors carry a lethal charge even after power is disconnected. You must discharge the capacitor before handling. Tools needed: insulated screwdriver, 1/4" nut driver, needle-nose pliers, multimeter with capacitance mode. Photograph all wiring connections before removal. If in doubt, call a licensed HVAC technician.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PH14NA01800GAAAA heat pump condensing unit. Always verify the MFD and voltage rating printed on your existing capacitor against the replacement before installation.
