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 Tempstar 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.

Overview

This is a genuine OEM single-pole definite-purpose contactor (part number 1050699) for the Tempstar TCH036AKA2 heat pump/condensing unit. The contactor is the electromechanical switch that energizes the compressor and outdoor fan motor when the thermostat calls for cooling. A 24-volt control signal pulls in the coil, closing the 25-amp line-voltage contacts that feed the compressor. A failed contactor typically causes a unit that hums but won't start, pitted or welded contacts that keep the compressor running, or a buzzing/chattering coil. Since the contacts arc each time the unit cycles, the contactor is among the most commonly replaced wear items on residential split systems.
