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 1-pole definite purpose contactor (part number 1172472) is the electrical switch that energizes the compressor and condenser fan motor in your Tempstar T2A336GKA100 condensing unit. When the thermostat calls for cooling, the 24-volt control circuit energizes the contactor coil, pulling the contacts closed to send line voltage to the compressor. Rated at 30 amps with a 24V coil and an integrated shunt, this contactor handles the high inrush current of a residential air conditioning compressor. Common failure symptoms include a unit that hums but won't start, pitted or welded contacts, a chattering coil, or an outdoor unit that runs continuously because the contacts are stuck closed. A burnt, corroded, or insect-damaged contactor is one of the most frequent causes of a no-cool service call.
