OEM Carrier Contactor CA16NA01800GAABA for Model CA16NA01800GAABA

This OEM Carrier contactor is the genuine electromechanical relay that delivers line voltage to the compressor and outdoor fan motor in your CA16NA01800GAABA air conditioner. A 24-volt control signal from the thermostat energizes the coil, pulling the contacts together to start the outdoor unit. Pitted, burned, or chattering contacts are a frequent cause of a unit that buzzes without running, won't start, or trips its breaker. Manufactured to Carrier's exact pole configuration, amp rating, and coil voltage, this contactor is matched to the CA16NA01800GAABA for solid contact and reliable cooling cycles. Installation is a moderate DIY task for those comfortable with 240V power: open the disconnect, photograph the wiring, move the leads one at a time, and mount the new contactor. Most homeowners finish in 20-30 minutes. A genuine OEM contactor protects your compressor from harmful voltage drop and chatter-related wear. In stock and ships same-day on orders placed before 3PM CST, so you can restore cooling fast. Guaranteed to fit your specific Carrier model.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CA16NA01800GAABA?
Yes. This is the factory-specified OEM contactor for the Carrier Model CA16NA01800GAABA. 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 CA16NA01800GAABA?
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?
