What amp contactor do I need for my Carrier system?

The correct replacement for Carrier model Condenser Model CA17NA04800GBAAA Unit is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Carrier equipment which lists the model number Condenser Model CA17NA04800GBAAA Unit.

My AC clicks but the compressor does not turn on. What is wrong?

Clicking from the outdoor unit without the compressor starting usually means a worn contactor. The contactor is the relay that sends power to the compressor. When its contacts are pitted or worn, it clicks but cannot establish a solid electrical connection. Other symptoms: visible pitting or burn marks on the contactor face, AC works intermittently, or buzzing from the contactor.

Is this contactor compatible with Bryant or Payne systems too?

Many Carrier parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

OEM Carrier Contactor for Condenser Model CA17NA04800GBAAA Unit

This OEM Carrier contactor is the factory-spec electrical switch that energizes the compressor and condenser fan on the Carrier CA17NA04800GBAAA unit. When your outdoor unit hums but won't start, the fan and compressor stay dead, or you hear chattering and see pitted, burned contacts, a failed contactor is almost always the cause. This direct-fit replacement matches the original's coil voltage, pole configuration, and amperage rating, so the unit pulls in cleanly and switches the high-voltage load without arcing. Installation is an easy-to-moderate repair: shut off power at the disconnect, photograph the wiring, transfer the line, load, and 24V coil leads to the identical terminals on the new contactor, and mount it in the control box. Most installs take 15-25 minutes. Always confirm power is off and verify the coil voltage matches before wiring. Genuine Carrier contactors handle inrush current to spec and resist contact welding better than generics. In stock and ships same-day on orders before 3PM CST.
