OEM Carrier Contactor Replacement Part for Model CA16NW01800GBAAA

Get your Carrier air conditioner cycling reliably again with this genuine OEM contactor, a direct replacement for condensing unit model CA16NW01800GBAAA. The contactor serves as the heavy-duty switch that energizes the compressor and outdoor fan motor on each thermostat cooling call and de-energizes them afterward. Failed contacts—pitted, stuck, or burnt—are among the most frequent causes of a no-start outdoor unit, persistent humming, or a system that won't turn off. Installing this factory-matched part restores correct switching and shields the compressor from electrical stress. The replacement is a moderate task for handy homeowners and a routine one for HVAC pros: shut off power at the disconnect, photograph the existing wiring, move each wire to the corresponding terminal on the new contactor, secure it, and re-energize. Most jobs take 20 to 30 minutes with basic tools. As authentic Carrier hardware, it ensures exact fit, rating, and longevity over universal alternatives. In stock and ships same-day for orders before 3PM CST.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CA16NW01800GBAAA?
Yes. This is the factory-specified OEM contactor for the Carrier Model CA16NW01800GBAAA. 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 CA16NW01800GBAAA?
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?
