The correct replacement for Tempstar model TCH936GKA100 — 1-Pole 30A 24V Coil | 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

The Tempstar OEM contactor (part #1172472) is a single-pole, 30-amp, 24-volt definite purpose contactor with a built-in shunt, specified for the TCH936GKA100 condensing unit. It acts as the electrically-operated switch that delivers line voltage to the compressor and condenser fan motor whenever the thermostat calls for cooling. The 24V coil pulls the contacts closed to power the motors; when the call ends, the coil releases and the contacts spring open. Worn contactors are a leading cause of no-cool service calls — symptoms include a compressor that won't start, a persistent hum or chatter, pitted or welded contacts, and arcing or burn marks at the terminals.
