OEM Carrier Start Capacitor 88-108 MFD 330V for Model PH14NA03000GAAAA

This OEM start capacitor (part number P281-8806) is the factory-specified replacement for the Carrier PH14NA03000GAAAA heat pump system. The start capacitor delivers the high-voltage burst of energy required to kick the compressor motor into motion on each cooling or heating cycle. When it fails or weakens, the compressor will attempt to start, hum under load, and either trip the overload protector or fail to run entirely — leaving you with no cooling or heating output. Replacing a failed start capacitor promptly protects the compressor from costly thermal damage caused by repeated hard-start attempts.

• Specs: 88–108 MFD (microfarad) | 330V rated | Round case, 2.06" diameter | Includes integrated bleed resistor for safe, automatic discharge | ±tolerance factory-matched
• OEM vs Generic: This is a genuine Carrier OEM part (Totaline/Factory Authorized Parts). OEM capacitors maintain precise MFD tolerances critical for compressor longevity. Generic alternatives often deviate ±10% MFD or more, accelerating compressor wear and increasing hard-start stress over time.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling terminals (use a resistor or insulated screwdriver). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter set to capacitance mode. Photograph all wiring before disconnecting. Confirm MFD and voltage ratings match your unit's data plate prior to installation.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.
