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.

Overview

This is the genuine OEM single-pole 30-amp contactor (part number 1172472) with a 24V coil and built-in shunt for the Tempstar TXH518GKA200 heat pump/condenser. The contactor is the electrically operated switch that delivers line voltage to the compressor and outdoor fan motor. When the thermostat calls for cooling or heat-pump operation, the 24V control signal energizes the coil and closes the contacts to start the compressor. Pitted, welded, or chattering contacts are among the most common no-cool/no-heat failures in the field. Typical symptoms include a buzzing outdoor unit, a compressor that won't start, burned or pitted contact points, or contacts that stick closed and keep the unit running.
