OEM Carrier Contactor Replacement for Model CH17NA02400GBAAA

This genuine OEM Carrier contactor is the workhorse relay that switches high-voltage power to your condenser's compressor and fan motor each time the thermostat calls for cooling. Over years of cycling, the contacts pit and burn while the coil weakens, leading to no-cool complaints, buzzing units, or contacts stuck closed that run the system non-stop. Engineered as a direct replacement for Carrier model CH17NA02400GBAAA, this contactor matches the original amperage rating, pole configuration, and coil voltage so it installs in the factory location without adapters. The swap is approachable for a handy homeowner or pro and usually takes 15-20 minutes: turn off power at the disconnect, move each wire one at a time to the identical terminal on the new part, and fasten it down. Confirm the unit is de-energized and discharge the run capacitor before handling any wiring. A new contactor delivers crisp, reliable switching and shields your compressor from the damaging effects of arcing and voltage drop. In stock and ships same-day on orders before 3PM CST.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CH17NA02400GBAAA?
Yes. This is the factory-specified OEM contactor for the Carrier Model CH17NA02400GBAAA. 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 CH17NA02400GBAAA?
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?
