OEM Carrier Start Capacitor 88-108 MFD 330V for Model PH13NR018000AHAA

This OEM start capacitor (part number P281-8806) is the factory-specified replacement for the Carrier PH13NR018000AHAA heat pump system. The start capacitor delivers the high-voltage surge needed to kick the compressor motor into rotation on every cooling or heating cycle. When it fails or degrades, the compressor will hum and struggle to start, trip the breaker, or simply refuse to run — leaving you with no cooling or heating output. Replacing it with the correct OEM part restores full compressor performance and protects the motor from damaging restart strain.

• Specs: 88–108 MFD (microfarad) | 330V rated | Round case, 2.06" diameter × 4.37" length | Includes integrated bleed resistor for safe discharge
• OEM vs Generic: This is a genuine Carrier/Totaline factory part, sourced from Carrier's approved capacitor manufacturer. OEM units hold tight MFD tolerance, protecting the compressor from the over-amp draw that generic wide-tolerance capacitors can cause.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling — the bleed resistor assists but do not rely on it alone. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Swap terminals one at a time to prevent miswiring.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
