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 40-amp definite purpose contactor (part number 1176763) is the switching relay that energizes the compressor and condenser fan on your Tempstar T2H360GKD300 heat pump. When the thermostat calls, the control coil pulls the contacts closed to pass line voltage to the compressor circuit. Contacts that pit, burn, or weld are a leading cause of no-cool/no-heat calls — symptoms include a humming unit that won't start, a system that won't shut off, or chattering at the contactor.
