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 primary switching relay for the Tempstar T2H348GKA200 heat pump. It is a single-pole, 30-amp device energized by a 24-volt control coil and includes an integrated shunt for reliable circuit operation. When your thermostat calls for cooling or heat-pump operation, the 24V coil pulls the contactor closed, sending line voltage to the compressor and condenser fan motor. A failed or pitted contactor is one of the most common reasons an outdoor unit goes silent. Typical failure symptoms include a humming outdoor unit that won't start, burnt or welded contacts, a buzzing chatter from the contactor, or the condenser running continuously because the contacts have welded shut.
