OEM Carrier Start Capacitor 175-216 MFD 330V for Model PH4ANG024000BCAA

This genuine OEM start capacitor (part number P281-1766) is the factory-specified replacement for the Carrier PH4ANG024000BCAA heat pump. The start capacitor delivers the high-voltage surge needed to kick the compressor motor into rotation during each startup cycle. Once the motor reaches operating speed, the start capacitor is switched out of the circuit. When this component fails, the compressor struggles to start, draws excessive amperage, trips the breaker, or simply refuses to run — leaving your system with no heating or cooling.

• Specs: 175–216 MFD (microfarad) capacitance range | 330V AC rated | Round case form factor | OEM factory-matched tolerance for precise, reliable operation
• OEM vs Generic: This is a genuine Carrier OEM part meeting exact factory specifications. Generic start capacitors commonly ship with loose MFD tolerances that force the compressor to work harder on every start, accelerating wear and shortening equipment life.
• Install difficulty: 3/5 — Discharge the capacitor fully before handling any terminals. Always cut power at the disconnect and confirm voltage is zero with a multimeter before proceeding. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter, insulated discharge resistor. Photograph all wiring before disconnecting. If uncertain, consult a licensed HVAC technician.
• Warranty: Backed by a 1-year OEM factory warranty. Orders placed by 3 PM ship same business day from our warehouse.

Compatibility: Engineered for the Carrier PH4ANG024000BCAA heat pump. Always cross-reference the MFD range (175–216) and voltage rating (330V) against the data plate on your unit before ordering.
