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 2-pole definite purpose contactor (part number 1059574) for the Tempstar TXA460AKA2 condensing unit. Rated for 40 amps with a 24-volt control coil, this contactor is the high-voltage switch that energizes the compressor and condenser fan motor on a thermostat cooling call. Both legs of line voltage are broken when the coil de-energizes, making the 2-pole design the standard for residential split-system condensers. As the contacts cycle they pit, burn, and eventually weld; the coil can also open or weaken. Typical failure symptoms include an outdoor unit that hums but won't start, buzzing or chattering contacts, visible arcing, and a compressor that runs continuously because the contacts have welded closed.
