What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T2H324GKA200 — 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

This is the OEM 1-pole 30-amp contactor with a 24V coil and shunt (part number 1172472) for the Tempstar T2H324GKA200 heat pump. The contactor is the heavy-duty relay that switches line power to the compressor and outdoor fan when the thermostat calls. Its 24V coil pulls the contacts closed; the shunt maintains a continuous path on the unswitched leg. Over time the contacts pit, burn, and weld, or the coil fails — leaving the outdoor unit dead, chattering, or stuck running. This 30A 1-pole contactor is a fast, inexpensive fix that prevents compressor and fan-motor damage from poor switching.
