OEM Carrier 2-Pole Contactor 24V Coil for Model CH13NA03600GACBA

This is the OEM replacement contactor (part number HN51KC024) for the Carrier CH13NA03600GACBA split-system air conditioner. The contactor is a high-voltage relay that receives a low-voltage (24V) signal from your thermostat and closes to send 240V power to the compressor and condenser fan motor. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — your outdoor unit will not energize at all, or may run continuously without responding to thermostat commands.

  • Specs: 2-pole configuration | 24V AC coil | 30–40A contact rating | Factory-matched for Carrier CH13NA03600GACBA | OEM part number HN51KC024
  • OEM vs Generic: This OEM contactor is manufactured to Carrier's exact electrical specifications, ensuring proper coil pull-in voltage and contact durability. Generic contactors may use lower-grade silver-alloy contacts that pit faster under load, leading to premature failure and potential compressor damage.
  • Install difficulty: 2/5 — Disconnect and lock out power at the disconnect box 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. Note: line-voltage terminals remain energized until the disconnect is pulled.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed specifically for the Carrier CH13NA03600GACBA 3-ton single-stage split-system condenser. Verify the OEM part number HN51KC024 on your existing contactor's label or your unit's wiring diagram before ordering. If you have any fitment questions, our HVAC parts specialists are available to confirm compatibility before you buy — no guesswork required.

Frequently Asked Questions

Does this Contactor fit my Carrier CH13NA03600GACBA?
Yes. This is the factory-specified OEM contactor for the Carrier CH13NA03600GACBA. 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 CH13NA03600GACBA?
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?
