OEM Carrier Contactor CA16NA01800GAAAA for Model CA16NA01800GAAAA

This OEM Carrier contactor is the genuine power switch that sends line voltage to the compressor and condenser fan motor in your CA16NA01800GAAAA condensing unit. When the thermostat calls for cooling, the 24-volt coil energizes and closes the contacts, starting the outdoor equipment. Failing contacts that are pitted, welded, or chattering commonly cause a unit that hums but won't start, cools poorly, or cycles on and off rapidly. Built to Carrier's exact amperage, pole, and coil-voltage specifications, this contactor matches the CA16NA01800GAAAA precisely for dependable seating and clean electrical contact. Installation is a moderate DIY job for those comfortable working around 240V: shut off the disconnect, photograph the existing wiring, transfer the leads one at a time, and secure the new contactor. Most homeowners complete it in 20-30 minutes. Choosing a true OEM part protects your compressor from voltage drop and chatter-induced wear. In stock and ships same-day when you order before 3PM CST, so cooling returns quickly. Backed by our exact-fit guarantee for your Carrier model.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CA16NA01800GAAAA?
Yes. This is the factory-specified OEM contactor for the Carrier Model CA16NA01800GAAAA. 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 CA16NA01800GAAAA?
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.
