OEM Carrier Start Capacitor P281-1766 for Model PH15NA01800GBAAA

This is the factory OEM start capacitor for the Carrier PH15NA01800GBAAA packaged heat pump unit. The start capacitor provides the high-torque electrical boost the compressor motor needs during startup. Without a functioning start capacitor, the compressor will struggle to start, draw excessive amperage, hum without engaging, or trip the breaker repeatedly — all signs of a failed or weak capacitor that needs immediate replacement.

• Specs: OEM Part Number P281-1766 | Factory-matched capacitance and voltage rating | Engineered to exact Carrier tolerances for the PH15NA01800GBAAA platform
• OEM vs Generic: This is a genuine OEM Carrier capacitor — not an aftermarket substitute. OEM units deliver factory-spec capacitance tolerance (±5% or better), reducing compressor wear and extending equipment life versus generic alternatives that often drift ±10% or more out of the box.
• Install Difficulty: 2/5 — Always disconnect power and discharge any residual voltage from the old capacitor before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring before disconnecting terminals.
• Warranty: 1-year OEM factory warranty coverage. Orders placed before cutoff ship the same business day from our warehouse.

Compatibility: Designed as the direct OEM replacement for Carrier model PH15NA01800GBAAA. Always verify the capacitance (MFD) and voltage ratings on your unit's data plate match this part before ordering.
