OEM Carrier Dual Run & Start Capacitor Kit for Model CA16NA02400GAAAA

This OEM-matched capacitor kit includes both the dual run capacitor (P291-3553RS) and the start capacitor (P281-1766) factory-specified for the Carrier CA16NA02400GAAAA split-system air conditioner. Capacitors store and release the electrical charge needed to start and sustain the compressor and condenser fan motor. A failing dual run capacitor typically causes a loud hum with no motor movement or repeated short-cycling, while a weak start capacitor results in a hard-starting or locked-rotor compressor that trips the breaker. Replacing both at once is best practice — if one has failed, the other is under equal stress.

• Specs: P291-3553RS — Dual Run Capacitor, round case, 370V/440V rated, ±5% OEM tolerance | P281-1766 — Start Capacitor, electrolytic, high-surge duty rated | Both factory-matched to Carrier CA16NA02400GAAAA specifications
• OEM vs Generic: OEM capacitors are manufactured to exact factory MFD tolerances (±5%), protecting your compressor and fan motor from voltage stress. Generic replacements often carry ±10% tolerance, which accelerates winding wear and shortens equipment life — especially in high-ambient conditions where the CA16NA series operates.
• Install Difficulty: 2/5 — Always disconnect power at the breaker and discharge capacitor terminals with an insulated resistor or discharge tool before handling. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before removing the old unit. The start capacitor may also have a hard-start relay — inspect and replace if worn.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty against defects. Orders ship same business day from our climate-controlled warehouse. Includes both P291-3553RS and P281-1766 in a single shipment.

Compatibility: This kit is engineered for the Carrier CA16NA02400GAAAA 2-ton, 16 SEER single-stage split-system condenser. Always verify the MFD rating and voltage printed on your existing capacitors against your unit's data plate before installing. Our fitment team is available to confirm compatibility before you order — no guesswork required.
