What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H342GKA200 — 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. You can verify this by checking the data plate on your Tempstar equipment which lists the model number T4H342GKA200 — 1-Pole 30A 24V w/ Shunt | 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 is a genuine OEM 1-pole, 30-amp definite purpose contactor with a 24-volt coil and integrated shunt, ICP/Tempstar part number 1172472, built for the Tempstar T4H342GKA200 heat pump. The contactor is the electromechanical switch that energizes the compressor and condenser fan motor each time your thermostat calls for cooling or heating. When the low-voltage coil receives 24V from the control circuit, the contactor pulls in and routes high-voltage line power to the outdoor unit. The built-in shunt provides a controlled current path that helps protect the contacts during switching. Because the contacts cycle thousands of times per season, they are one of the most common wear items in any condensing unit — pitted, burned, or welded contacts cause hard starts, chattering, or a unit that will not run at all.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter at the contactor line terminals.
Access — Remove the condensing unit service panel.
Document — Photograph all line, load, and 24V coil wires before disconnecting anything.
Remove — Transfer wires one at a time, or label them, then unscrew the old contactor from the bracket.
Install — Mount the new 1172472, reconnect line/load and the 24V coil leads per your photo, and confirm the shunt connection.
Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the compressor and fan start.
