OEM Carrier Start Capacitor 175-216 MFD 330V for Model PH4ANG018000BCAA

This genuine OEM start capacitor (part number P281-1766) is the factory-specified replacement for the Carrier PH4ANG018000BCAA heat pump system. The start capacitor delivers the high-voltage charge burst needed to initiate compressor rotation. When this component fails, the compressor receives power but cannot overcome starting inertia — resulting in a humming sound, a tripped breaker, or a system that simply won't cool or heat. Replacing this capacitor promptly prevents compressor burnout, which is a far more costly repair.

• Specs: 175–216 MFD (microfarad) | 330V rated | Round case form factor | Factory-matched capacitance range for reliable motor start
• OEM vs Generic: This is a genuine Carrier OEM part sourced to exact factory tolerances. Generic start capacitors often ship with wider MFD variance, leading to hard-start stress on the compressor and premature failure.
• Install difficulty: 2/5 — Always discharge the capacitor fully before touching terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting. Capacitor should be tested with a multimeter set to capacitance mode before condemning.
• Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed for the Carrier PH4ANG018000BCAA heat pump unit. Always verify the MFD rating and voltage printed on your existing capacitor's label against your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you purchase — no guesswork required.
