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 Tempstar 1-pole 30-amp contactor with shunt (OEM part 1172472) is the high-voltage switch that powers the compressor and outdoor fan on the T2H342GKB200. A 24V signal from the control board energizes the coil, pulling the contacts closed to start the outdoor unit. Over time the contacts pit, burn, or weld, and the coil can fail open. Symptoms include a unit that won't start, a loud chattering or buzzing at the contactor, contacts that stay stuck closed so the unit never shuts off, or visible arcing and burnt terminals.
