OEM Carrier Start Capacitor P281-8806 for Model PH13NR048000AAAA

This is the factory OEM start capacitor for the Carrier PH13NR048000AAAA heat pump system, supplied under part number P281-8806. The start capacitor delivers the high-torque electrical boost the compressor motor needs during startup. Without a functioning start capacitor, the compressor struggles to turn over, draws excessive amperage, and will either trip the breaker or trigger a thermal overload — leaving you with no cooling or heating. A failed start capacitor typically presents as a hard-starting compressor, a unit that hums but won't start, or a system that trips the breaker repeatedly on startup.

• Specs: OEM-matched capacitance (µF) and voltage rating | Factory-specified for Carrier PH13NR048000AAAA | Tight tolerance construction for reliable compressor start performance
• OEM vs Generic: This OEM P281-8806 meets Carrier's exact electrical tolerances. Aftermarket start capacitors often deviate in µF rating and voltage surge capacity, risking compressor damage and shortened service life.
• Install difficulty: 2/5 — Always disconnect power and discharge the capacitor before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter. Photograph all wiring connections prior to removal for safe reinstallation.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed specifically for the Carrier PH13NR048000AAAA residential heat pump. Always verify the µF and voltage rating on your unit's data plate before ordering to confirm fitment. Our parts specialists are available to verify compatibility before you buy — no guesswork required.
