OEM Carrier Start Capacitor 88-108 MFD 330V for Model PH12NA024000AAAA

This OEM start capacitor (part number P281-8806) is the factory-specified replacement for the Carrier PH12NA024000AAAA heat pump system. The start capacitor delivers the initial surge of electrical energy required to spin up the compressor from a standstill. Without a functioning start capacitor, the compressor motor stalls on startup — you may hear a brief hum or clicking followed by a tripped breaker or system lockout. If your unit attempts to start but immediately shuts down, or the compressor is completely unresponsive, a failed start capacitor is one of the most common culprits.

• Specs: 88–108 MFD (microfarad) | 330V rated | Round case | 2.06" diameter × 4.37" height | Includes built-in bleed resistor for safe discharge | ±10% MFD tolerance, factory-matched
• OEM vs Generic: This is a genuine Carrier OEM part (Totaline® / Factory Authorized Parts). OEM start capacitors are built to exact factory MFD and voltage tolerances, protecting your compressor from stress caused by under- or over-charged starts. Note: Carrier sources capacitors from select manufacturers — the capacitor label may bear the OEM supplier name rather than Carrier branding.
• Install difficulty: 2/5 — Always discharge the capacitor before handling using an insulated resistor or discharge tool. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before removal. Start capacitors are typically wired in series with a start relay — confirm relay condition as well.
• Warranty: 1-year OEM factory warranty against defects. Orders ship same business day from our warehouse when placed before cutoff.
