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 TCA230AKA5 condensing unit. The contactor is the electromagnetic switch that energizes your compressor and condenser fan motor. When the thermostat calls for cooling, a 24-volt signal pulls in the contactor coil, closing the 25-amp line-voltage contacts and starting the outdoor unit. Over time the contacts pit and burn from arcing, and the coil can fail open or stick closed. A bad contactor is one of the most common causes of an outdoor unit that won't start, hums without running, or runs continuously even after the thermostat is satisfied. This 1-pole, 25A, 24V coil contactor is the exact replacement specified for this model.
