OEM Carrier 2-Pole Contactor 24V Coil for Model CH13NA03000GAABA

This OEM contactor is the factory-specified replacement for the Carrier CH13NA03000GAABA split-system air conditioner. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes to deliver line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or contact welding — the result is an AC unit that won't energize at all, runs continuously without shutting off, or trips the breaker repeatedly.

  • Specs: 2-pole configuration | 24V AC coil | 30A contact rating | 240V line voltage rated | OEM part number HN51KC024 | Factory-matched contact material for long service life
  • OEM vs Generic: This is an authentic Carrier OEM contactor sourced directly from the factory. Generic contactors frequently use inferior contact alloys that pit and arc faster under load, leading to premature failure. OEM ensures the exact coil pull-in voltage and contact resistance your control board expects.
  • Install difficulty: 2/5 — Always disconnect power at the breaker and wait for capacitors to discharge before beginning. Tools needed: 1/4" and 5/16" nut drivers, flathead screwdriver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting terminals.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Ships same business day from our climate-controlled warehouse.

Compatibility: Designed for the Carrier CH13NA03000GAABA split-system condenser. Verify your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering. Our HVAC parts specialists are available to confirm fitment — order with confidence and get back to cool faster.

Frequently Asked Questions

Does this Contactor fit my Carrier CH13NA03000GAABA?
Yes. This is the factory-specified OEM contactor for the Carrier CH13NA03000GAABA. 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 CH13NA03000GAABA?
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?
