OEM Carrier Contactor Replacement for Model CH17NA04800GBAAA

This genuine OEM Carrier contactor is the electrically-operated switch that controls power to your condenser's compressor and outdoor fan motor. When your 24V thermostat signal calls for cooling, the contactor's coil energizes and closes the contacts, sending line voltage to the unit. Worn, pitted, or chattering contacts are a leading cause of no-cool conditions and hard starts. This contactor is engineered as a direct-fit replacement for Carrier model CH17NA04800GBAAA, matching the original amperage, pole configuration, and coil voltage for reliable operation. Installation is straightforward for an experienced DIYer or HVAC technician: shut off power at the disconnect, photograph and transfer the wiring one lead at a time, and secure the new contactor in place — typically a 15-20 minute job. Always confirm power is off and discharge the run capacitor before servicing. Restore long-lasting, quiet switching and protect your compressor from voltage drop and arcing. In stock and ships same-day when you order before 3PM CST.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CH17NA04800GBAAA?
Yes. This is the factory-specified OEM contactor for the Carrier Model CH17NA04800GBAAA. 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 CH17NA04800GBAAA?
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?
