OEM Carrier Contactor Replacement Part for Model CA16NW02400GAAAA

This genuine OEM Carrier contactor is the precise replacement for condensing unit model CA16NW02400GAAAA. The contactor is the electrically operated switch that delivers line voltage to the compressor and condenser fan motor whenever the thermostat calls for cooling, then cuts power when the call ends. Pitted, corroded, or welded contacts commonly cause a unit that hums without starting, chatters, or refuses to shut off, and replacing the contactor clears these symptoms while protecting the compressor from harmful electrical conditions. The job is moderate in difficulty and within reach of confident DIYers and all technicians: turn off power at the outdoor disconnect, photograph the wiring, transfer each lead to its matching terminal, mount the new contactor, and restore power. It usually takes 20 to 30 minutes with basic hand tools. Because this is a true Carrier OEM part, you get exact voltage, amperage, and pole matching plus full original service life. In stock and ships same-day on orders placed before 3PM CST.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CA16NW02400GAAAA?
Yes. This is the factory-specified OEM contactor for the Carrier Model CA16NW02400GAAAA. 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 CA16NW02400GAAAA?
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?
