OEM Carrier Start Capacitor 175-216 MFD 330V for Model PH15NB02400GBAAA

This genuine OEM start capacitor (part number P281-1766) is the factory-specified replacement for the Carrier PH15NB02400GBAAA heat pump. The start capacitor provides the high-voltage boost the compressor motor needs during startup. Without a functioning start capacitor, the compressor struggles to overcome inertia — resulting in hard starts, tripped breakers, or a compressor that hums but never engages. Left unaddressed, a failed start capacitor places tremendous thermal stress on the compressor windings, dramatically shortening compressor life.

• Specs: 175–216 MFD (microfarad) | 330VAC rated | Round case design | Factory-matched capacitance range ensures correct startup torque
• OEM vs Generic: This is a genuine Carrier OEM part (P281-1766), sourced and tested to factory specifications. Generic start capacitors frequently fall outside the rated MFD tolerance window, causing repeated hard-start conditions and premature compressor failure.
• Install difficulty: 2/5 — Discharge the capacitor fully before handling any terminals. Tools needed: insulated screwdriver, needle-nose pliers, multimeter. Always photograph existing wiring before disconnecting leads. Capacitor is located inside the electrical compartment of the outdoor unit.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
