OEM Carrier Contactor Replacement Part for Model CA16NW04300GBAAA

Keep your Carrier air conditioner starting on demand with this genuine OEM contactor built as a direct replacement for model CA16NW04300GBAAA. The contactor acts as the heavy-duty switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. Over time the contacts pit, corrode, or stick, causing no-start conditions, chattering, or a unit that runs continuously. This factory-matched part restores the correct coil voltage and contact rating so your system cycles cleanly and protects the compressor from electrical stress. Installation is a moderate task suited to confident DIYers and HVAC pros alike: disconnect power at the outdoor shutoff, photograph the existing wiring, transfer each lead to the matching terminal, mount the new contactor, and restore power. The job typically takes 20 to 30 minutes with basic tools. Using a true Carrier OEM component ensures exact fit and full service life rather than the shorter lifespan of universal parts. In stock and ships same-day on orders placed before 3PM CST.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CA16NW04300GBAAA?
Yes. This is the factory-specified OEM contactor for the Carrier Model CA16NW04300GBAAA. 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 CA16NW04300GBAAA?
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?
