What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TXH536GKA200 — 24V Coil w/ Shunt | 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.

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 is the genuine OEM Tempstar contactor, part number 1172472, a 1-pole, 30-amp contactor with a 24V coil and shunt, for the TXH536GKA200 heat pump. The contactor is the high-voltage switch that powers the compressor and outdoor fan. When the thermostat calls for cooling or heating, the 24V control signal energizes the coil, pulling the contacts closed to send line voltage to the compressor. Over thousands of cycles the contacts pit, burn, or weld, and the coil can fail open. The integrated shunt provides a controlled path that helps the unit run safely. This factory-spec 30A, 24V contactor is the correct drop-in replacement for reliable, safe switching.
