OEM Carrier 2-Pole Contactor HN51KC024 for Model CA16NW03000GAAAA

This is the factory OEM replacement contactor (part number HN51KC024) for the Carrier CA16NW03000GAAAA split-system air conditioner. The contactor is the high-voltage relay that completes the electrical circuit to your compressor and condenser fan motor each time the thermostat calls for cooling. When a contactor fails — due to pitted contacts, a burned coil, or stuck contacts — your outdoor unit will either refuse to start entirely or run continuously without responding to thermostat signals. Replacing a worn contactor is one of the most common and cost-effective AC repairs you can perform.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-matched contact rating | Direct OEM replacement for part number HN51KC024
  • OEM vs Generic: This OEM contactor uses factory-spec contact material rated to Carrier's exact switching load. Generic contactors frequently use undersized contact surfaces that pit and fail prematurely under compressor inrush current, leading to repeat failures within a single season.
  • Install difficulty: 3/5 — Always disconnect power at the disconnect box and confirm voltage is zero with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor.
  • Warranty: 1-year OEM factory warranty. Orders placed by 3 PM EST ship the same business day from our climate-controlled warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier CA16NW03000GAAAA split-system air conditioner. Always verify the coil voltage and pole configuration on your unit's data plate or existing contactor label before ordering. Not sure it fits? Our HVAC parts specialists confirm fitment before you buy — no guesswork, no returns.

Frequently Asked Questions

Does this Contactor fit my Carrier CA16NW03000GAAAA?
Yes. This is the factory-specified OEM contactor for the Carrier CA16NW03000GAAAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the contactor on my Carrier CA16NW03000GAAAA?
Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Open condensing unit panel. Step 3: Photograph ALL wiring on the contactor. Step 4: Label each wire with tape. Step 5: Disconnect wires and remove old contactor. Step 6: Mount new contactor, reconnect wires matching your photo. Step 7: Restore power and test.
My AC clicks but the compressor won’t turn on. What’s wrong?
Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.
Is this contactor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier contactor?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
How fast does National HVAC Parts ship?
