OEM Carrier Contactor Replacement for Model CA13NA0420NGAABA

This OEM Carrier contactor is the factory-specified replacement for the Carrier CA13NA0420NGAABA 13 SEER condensing unit. The contactor acts as the main electrical switch, energizing the compressor and outdoor fan motor whenever the thermostat calls for cooling. Pitted, corroded, or welded contacts are a leading cause of no-cooling service calls, producing buzzing, chattering, or a system that runs continuously. This direct-replacement contactor matches the original coil voltage, pole count, and amperage so it installs without modification. The swap is among the simplest HVAC repairs and ideal for a confident DIYer: disconnect power, photograph the wiring, move each wire to the matching terminal, and mount the new contactor. Installing the genuine OEM part ensures clean, reliable switching and helps protect your compressor from damaging voltage spikes. All orders placed before 3PM CST ship the same day, so you can quickly restore comfort. Replacing an aging contactor proactively is inexpensive protection against far more expensive compressor and motor failures.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CA13NA0420NGAABA?
Yes. This is the factory-specified OEM contactor for the Carrier Model CA13NA0420NGAABA. 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 CA13NA0420NGAABA?
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?
