What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H342GKA100 — 1-Pole 30A 24V 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 a genuine OEM 1-pole, 30-amp definite purpose contactor with a 24-volt coil and integrated shunt, ICP/Tempstar part number 1172472, for the Tempstar T4H342GKA100 heat pump. The contactor is the electromechanical switch that energizes the compressor and condenser fan motor whenever the thermostat calls. When the 24V coil is energized, the contactor pulls in and passes high-voltage line power to the outdoor unit; the integrated shunt provides a controlled current path that helps protect the contacts during switching. Because the contacts cycle thousands of times each season, they are a leading wear item — pitted, burned, or welded contacts lead to hard starts, chattering, or a unit that won't run at all.
