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 genuine OEM single-pole contactor (part number 1172472) switches line power to the compressor and outdoor fan on the Tempstar TCH924GKA100 heat pump. Rated at 30 amps with a 24V coil and an integrated shunt, the contactor is the heavy-duty relay the thermostat energizes every time the system calls for cooling or heating. When the thermostat sends 24V to the coil, the contactor's contacts pull in and feed full line voltage to the unit. Over thousands of cycles the contacts pit, burn, or weld, and the coil can fail open — leaving you with a humming, chattering, or completely dead outdoor unit. Replacing a worn contactor is a fast, inexpensive repair that prevents compressor damage from low or chattering voltage.
