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 OEM definite-purpose contactor (part number 1172472) is the main switching relay for the Tempstar T2H348GKA100 heat pump. It is a single-pole, 30-amp device driven by a 24-volt control coil and includes an integrated shunt for dependable operation. On a thermostat call, the 24V coil closes the contactor and delivers line voltage to the compressor and condenser fan. Contactors wear out from arcing every time they cycle, making them one of the most common no-cool/no-heat failures. Typical symptoms include a humming outdoor unit that won't start, pitted or welded contacts, a buzzing chatter, or a condenser that runs continuously because the contacts have welded shut.
