OEM Carrier Contactor CA13NA01800GAAAA for Model CA13NA01800GAAAA

This genuine OEM Carrier contactor is the factory replacement switching relay for the Carrier CA13NA01800GAAAA condensing unit. The contactor uses a low-voltage thermostat signal to energize the high-voltage circuit that powers the compressor and condenser fan motor. Over time, contactor points pit, corrode, or weld shut from constant arcing, leading to a unit that won't start, won't shut off, or hums and chatters. Replacing a worn contactor restores reliable, safe operation and prevents damage to your compressor. This OEM part matches the original coil voltage, pole configuration, and amperage rating for an exact fit—no guesswork. Installation is easy: most homeowners complete it in 15–20 minutes by photographing the wiring, transferring leads one at a time, and securing the new contactor. Always disconnect power at the disconnect box before servicing. We stock only genuine Carrier parts for guaranteed compatibility and longevity. Order before 3PM CST and your contactor ships the same day, so your system is back up and cooling quickly.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CA13NA01800GAAAA?
Yes. This is the factory-specified OEM contactor for the Carrier Model CA13NA01800GAAAA. 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 CA13NA01800GAAAA?
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?
