What amp contactor do I need for my Carrier system?

The correct replacement for Carrier model Model CH16NA01800GAAAA 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 Model CH16NA01800GAAAA.

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 Replacement for Model CH16NA01800GAAAA

This genuine OEM Carrier contactor handles the critical job of switching high-voltage power to your compressor and outdoor fan motor every time the thermostat calls for cooling. Years of repeated cycling wear the contact surfaces and weaken the coil, which shows up as a buzzing outdoor unit, burned or welded contacts, or a system that won't kick on at all. Engineered as a direct-fit replacement for Carrier model CH16NA01800GAAAA, it matches the original's amp rating, pole configuration, and coil voltage so it drops into the factory location without adapters or rewiring. The installation suits a confident homeowner or technician and usually takes 15-20 minutes: turn off power at the disconnect, move each wire individually to the matching terminal, and bolt down the new contactor. Always verify the unit is de-energized and discharge the run capacitor before handling wiring. A new contactor brings back clean, reliable switching and protects your compressor from the wear caused by arcing and voltage drop. In stock and ships same-day on orders before 3PM CST.
