The correct replacement for Tempstar model TCA924GKA200 — 1-Pole 30A 24V Coil w/ Shunt | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications.

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 contactor (part number 1172472) is a 1-pole, 30-amp unit with a 24V coil and an integrated shunt, used on the Tempstar TCA924GKA200 condensing unit. The contactor is the electrically operated switch that closes the high-voltage circuit to the compressor and condenser fan whenever the 24V control circuit calls for cooling. Contactors wear out from arcing, pitted or welded contacts, and failed coils. A bad contactor shows up as a unit that won't start, chatters, or a compressor that won't shut off because the contacts have welded closed. The shunt provides the proper bypass path for this model's wiring.
