OEM Carrier Contactor CA16NA02400GAABA for Model CA16NA02400GAABA

This OEM Carrier contactor is the genuine power-switching relay that delivers line voltage to the compressor and condenser fan motor in your CA16NA02400GAABA air conditioner. When the thermostat calls for cooling, the 24-volt coil energizes and pulls the contacts closed, starting the outdoor unit. Burned, pitted, or chattering contacts commonly cause a system that won't start, hums without running, or cycles erratically. Manufactured to Carrier's exact pole configuration, amperage rating, and coil voltage, this contactor is a precise match for the CA16NA02400GAABA, ensuring solid contact and reliable starts. Installation is a moderate DIY task for those comfortable around 240V: open the disconnect, photograph the existing wiring, move the leads one at a time to the new contactor, and mount it. Most homeowners finish in about 20-30 minutes. A true OEM contactor protects your compressor from damaging voltage drop and chatter wear. In stock and ships same-day on orders before 3PM CST, so you can get cool air back quickly. Backed by our exact-fit guarantee for your Carrier model.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CA16NA02400GAABA?
Yes. This is the factory-specified OEM contactor for the Carrier Model CA16NA02400GAABA. 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 Model CA16NA02400GAABA?
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.
