OEM Carrier Contactor Replacement Part for Model CA16NW01800GAAAA

This authentic OEM Carrier contactor is engineered as an exact replacement for condensing unit model CA16NW01800GAAAA. Acting as the primary power-switching relay, it closes to feed line voltage to the compressor and condenser fan motor when your thermostat calls for cooling and opens to stop them. Burnt, buzzing, or welded contacts frequently cause an outdoor unit that won't start, runs nonstop, or makes a loud humming noise, and a fresh contactor resolves these faults while protecting the compressor windings from damage. The replacement is a moderate-difficulty job suitable for confident DIYers and standard for technicians: disconnect power at the outdoor shutoff, photograph the wiring for reference, transfer the leads one terminal at a time, mount the new contactor, and restore power. Expect about 20 to 30 minutes with common hand tools. Genuine Carrier construction guarantees the correct coil voltage, contact rating, and physical fit for long, dependable service. In stock and ships same-day on orders placed before 3PM CST.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CA16NW01800GAAAA?
Yes. This is the factory-specified OEM contactor for the Carrier Model CA16NW01800GAAAA. 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 CA16NW01800GAAAA?
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?
