OEM Carrier Start Capacitor 175-216 MFD 330V for Model PH12NA04800GADAA

This is the genuine OEM start capacitor (part number P281-1766) factory-specified for the Carrier PH12NA04800GADAA heat pump / air conditioner. The start capacitor delivers a high-voltage burst of electrical energy to the compressor motor at the moment of startup, then drops out of the circuit once the motor reaches operating speed. Without a functioning start capacitor, the compressor will hum, fail to spin up, trip the overload protector, or refuse to start entirely — leaving you with no cooling or heating and a potential compressor burnout if ignored.

• Specs: 175–216 MFD (microfarad) | 330V AC rated | Round case form factor | Factory-matched capacitance range per Carrier specification
• OEM vs Generic: This is a genuine Carrier-sourced OEM unit — not an aftermarket substitute. OEM start capacitors maintain exact capacitance tolerances critical for clean compressor starts, reducing inrush stress and extending compressor life versus generic ±10–15% alternatives.
• Install difficulty: 2/5 — Disconnect power and discharge the capacitor completely before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Always photograph all wiring connections before removal.
• Warranty & Shipping: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH12NA04800GADAA unit. Verify the MFD range and voltage rating on your existing capacitor's label or equipment data plate before ordering. Not sure it fits? Our HVAC parts specialists confirm fitment before you buy — no guesswork, no return hassle.
