OEM Carrier Contactor 2-Pole 24V Coil for Model CH13NA03600GAABA

This OEM contactor (part# HN51KC024) is the factory-specified replacement for the Carrier CH13NA03600GAABA split-system air conditioner. The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when you call for cooling, the contactor closes and delivers line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an AC system stops responding entirely, hums without starting, or runs continuously without shutting off. Burned or pitted contacts are the telltale signs of a contactor ready for replacement.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30–40 amp rating | Direct factory replacement for OEM part# HN51KC024
  • OEM vs Generic: This OEM contactor uses factory-grade silver-alloy contact points engineered to Carrier's exact arc-resistance and pull-in voltage specs. Generic contactors often use inferior contact materials that pit and fail prematurely — especially under the high cycling demands of a 3-ton condenser.
  • Install difficulty: 2/5 — Shut off power at the disconnect and breaker panel before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Always photograph wiring before removing old contactor. One-for-one terminal swap; coil and load terminals are clearly labeled.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our stocked warehouse.

Compatibility: Engineered specifically for the Carrier CH13NA03600GAABA 3-ton split-system condenser. Verify coil voltage (24V) and pole configuration on your unit's data plate before ordering. Not sure it's the right part? Our HVAC parts team confirms fitment before you buy — contact us anytime.

Frequently Asked Questions

Does this Contactor fit my Carrier CH13NA03600GAABA?
Yes. This is the factory-specified OEM contactor for the Carrier CH13NA03600GAABA. 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 CH13NA03600GAABA?
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?
