OEM Carrier Contactor CA16NA02400GAAAA for Model CA16NA02400GAAAA

This OEM Carrier contactor is the genuine high-voltage switch that powers the compressor and condenser fan motor in your CA16NA02400GAAAA condensing unit. When your thermostat signals for cooling, the 24-volt coil energizes and snaps the contacts closed, sending line voltage to the outdoor equipment. Over time the contacts pit, weld, or chatter, leaving you with a unit that hums but won't start, fails to cool, or short-cycles. Made to Carrier's exact amperage, pole count, and coil voltage, this contactor matches the CA16NA02400GAAAA precisely for dependable seating and full electrical contact. Replacement is a moderate DIY job for anyone comfortable with 240V: shut off the disconnect, photograph the wiring layout, transfer each lead to the new contactor, and secure it in place. Most homeowners are done in 20-30 minutes. Installing a true OEM part shields your compressor from voltage drop and premature wear caused by failing contacts. In stock and ships same-day when ordered before 3PM CST. Backed by our fit guarantee for your Carrier model.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CA16NA02400GAAAA?
Yes. This is the factory-specified OEM contactor for the Carrier Model CA16NA02400GAAAA. 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 CA16NA02400GAAAA?
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?
