OEM Carrier 2-Pole Contactor 24V Coil for Model CA13NA03600GACBA

This is the factory OEM replacement contactor (part number HN51KC024) for the Carrier CA13NA03600GACBA split-system air conditioner. The contactor is a high-voltage relay that controls power to the compressor and condenser fan motor. When the thermostat calls for cooling, the 24V control circuit energizes the contactor coil, closing the contacts and delivering line voltage to the system. A failed contactor is one of the most common reasons an AC unit won't turn on — symptoms include a humming noise from the contactor, pitted or burned contact points, or a compressor that simply refuses to start despite the thermostat calling for cooling.

  • Specs: 2-pole configuration | 24V coil voltage | 30-amp contact rating | Direct OEM replacement for part number HN51KC024 | Factory-matched electrical tolerances
  • OEM vs Generic: OEM contactors use silver-alloy contact tips rated for thousands of switching cycles. Generic contactors frequently use lower-grade contact materials that pit and burn prematurely, leading to repeat failures within a single cooling season.
  • Install difficulty: 3/5 — Always shut off power at the disconnect and verify zero voltage with a multimeter before beginning work. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship the same business day from our climate-controlled warehouse.

Compatibility: Designed specifically for the Carrier CA13NA03600GACBA single-stage split-system condenser. Verify coil voltage and pole configuration on your unit's data plate before ordering. Our HVAC parts specialists are available to confirm fitment — reach out before you order if you have any questions. In stock and ready to ship today.

Frequently Asked Questions

Does this Contactor fit my Carrier CA13NA03600GACBA?
Yes. This is the factory-specified OEM contactor for the Carrier CA13NA03600GACBA. 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 CA13NA03600GACBA?
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?
