OEM Carrier Start Capacitor 88-108 MFD 330V for Model PH14NA018000AAAA

This is the factory-authorized OEM start capacitor (part number P281-8806) for the Carrier PH14NA018000AAAA heat pump. The start capacitor provides the short-duration electrical boost the compressor needs to overcome inertia and reach operating speed on each cooling or heating cycle. When this capacitor fails, the compressor struggles to start, draws excessive locked-rotor amperage, and will typically trip on thermal overload — leaving you with a system that hums briefly and then shuts off, or one that won't start at all. Replacing a failed start capacitor promptly also protects your compressor from repeated hard-start stress and premature wear.

• Specs: 88–108 MFD (microfarad) | 330V rated | 2.06" diameter × 4.37" length | Round case with bleed resistor | Factory-matched tolerance
• OEM vs Generic: This is a genuine Carrier-sourced capacitor meeting exact factory MFD tolerance. Off-brand capacitors often carry a wide ±10% tolerance that can stress your compressor motor windings and shorten system life.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting the old unit.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Fits Carrier model PH14NA018000AAAA heat pump condensing units. Always verify the MFD range and voltage rating on your unit's data plate or existing capacitor before ordering.
