OEM Carrier 2-Pole Contactor 24V Coil for Model CA13NA03600GAABA

This OEM contactor is the factory-specified replacement for the Carrier CA13NA03600GAABA split-system air conditioner. The contactor is the high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to power the compressor and condenser fan motor. When it fails, the unit may not respond to a call for cooling at all, run continuously without shutting off, or show visible pitting and burning on the contact points.

  • Specs: 2-pole design | 24V coil voltage | 30-amp rating | OEM part number HN51KC024 | Factory-matched contact material and coil resistance
  • OEM vs Generic: This OEM contactor is manufactured to Carrier's exact contact gap, coil pull-in voltage, and ampacity specifications. Generic contactors often use lower-grade contact alloys that pit and weld prematurely under high cycling loads common in residential AC operation.
  • Install difficulty: 2/5 — Always disconnect power at the disconnect box and verify zero voltage with a multimeter before proceeding. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting terminals to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered as a direct OEM replacement for Carrier CA13NA03600GAABA 3-ton split-system condensers. Cross-references OEM part number HN51KC024. Always verify coil voltage and pole configuration on your unit's data plate before ordering. Our fitment specialists are available to confirm compatibility before you buy — same-day shipping available on in-stock orders.

Frequently Asked Questions

Does this Contactor fit my Carrier CA13NA03600GAABA?
Yes. This is the factory-specified OEM contactor for the Carrier CA13NA03600GAABA. 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 CA13NA03600GAABA?
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.
