OEM Carrier Start Capacitor 88-108 MFD 330V for Model PH12NA024000ADAA

This is the genuine OEM start capacitor (Part #P281-8806) factory-specified for the Carrier PH12NA024000ADAA heat pump system. The start capacitor delivers the high-torque electrical boost needed to kick the compressor into motion on every cooling or heating cycle. Without a functioning start capacitor, the compressor will hum under load but fail to turn over — causing the system to trip on thermal overload or lock out entirely. If your Carrier unit is failing to start, short-cycling, or tripping the breaker repeatedly, a failed start capacitor is one of the first components to test.

• Specs: 88–108 MFD (microfarad) | 330V rated | Round case — 2.06" diameter × 4.37" length | Includes integrated bleed resistor for safe discharge | 50/60 Hz compatible
• OEM vs Generic: This is a genuine Carrier-sourced OEM capacitor manufactured to exact factory MFD tolerance. Generic start capacitors can drift outside the rated MFD range, causing hard-start stress on your compressor and significantly shortening its service life.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling (the bleed resistor assists, but verify with a multimeter). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter set to capacitance. Photograph all wiring connections before disconnecting terminals.
• Warranty: 1-year OEM factory warranty against defects. Orders ship same business day from our stocked warehouse.
