OEM Carrier 2-Pole Contactor 24V Coil for Model CH13NA02500GABAA

This OEM contactor is the factory-specified replacement for the Carrier CH13NA02500GABAA split-system air conditioner. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes to send line voltage to the compressor and condenser fan motor. When it fails — due to pitted contacts, a stuck plunger, or a burned coil — the outdoor unit simply won't respond to a cooling call, leaving you with warm air and a running air handler.

  • Specs: 2-pole configuration | 24V coil voltage | 30–40A contact rating | Direct OEM replacement for part number HN51KC024
  • OEM vs Generic: This factory OEM unit uses silver-alloy contacts rated to factory specifications. Generic contactors often use lower-grade contact material that arcs and pits faster, especially under Florida or Southwest summer loads.
  • Install Difficulty: 2/5 — Always shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. The job typically takes 20–30 minutes for a competent DIYer or technician.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier CH13NA02500GABAA 2-ton split-system condenser. Verify coil voltage and pole configuration on your unit's data plate before ordering. OEM part number HN51KC024 is the exact factory match. Have questions about fitment? Our HVAC parts specialists confirm compatibility before you buy — no guesswork.

Frequently Asked Questions

Does this Contactor fit my Carrier CH13NA02500GABAA?
Yes. This is the factory-specified OEM contactor for the Carrier CH13NA02500GABAA. 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 CH13NA02500GABAA?
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?
