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 genuine OEM single-pole definite-purpose contactor (part number 1050699, CONTACTOR 1P 25A 24V) is the electrical relay that switches line voltage to the compressor and condenser fan in the Tempstar TCH018AKD1 heat pump. When the thermostat closes the 24V control circuit, the contactor's coil pulls the contacts together, energizing the outdoor unit. Contactors are high-wear items: every cooling or heating cycle arcs the contacts slightly, and over years they pit, burn, or weld. A failed contactor is one of the most common no-cooling service calls — symptoms range from a buzzing/chattering coil to contacts that stick closed (unit won't shut off) or fail to pull in (unit won't start).
