What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TCH924GKA200 — OEM 1172472 | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Tempstar equipment which lists the model number TCH924GKA200 — OEM 1172472 | Ships Today.

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 Tempstar 1-pole, 30-amp definite purpose contactor (OEM part 1172472) is the electromagnetic relay that switches line power to the compressor and condenser fan motor. When the thermostat sends a 24V call, the contactor coil energizes and pulls the contacts closed, delivering high voltage to the outdoor unit. This OEM version includes a factory shunt for proper circuit routing. Rated for a 24V coil and 30A contacts, it matches the factory specification. Pitted, welded, or chattering contacts are a frequent cause of no-cool calls and compressor lockout.
