What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H430GKA100 — 24V Coil | 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 T4H430GKA100 — 24V Coil | 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 genuine OEM single-pole 30-amp definite-purpose contactor with an integrated shunt is the direct replacement for the Tempstar T4H430GKA100. The contactor is the electrically operated switch that powers the compressor and condenser fan motor. When the thermostat calls for cooling or heat-pump operation, the 24V coil pulls the contacts closed and sends line voltage to the outdoor unit. Pitted, welded, or chattering contacts cause hard starts, intermittent operation, or a unit that won't start at all. The built-in shunt provides a controlled current path that improves switching reliability on single-pole designs.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker; verify zero voltage with a multimeter.
Access — Remove the condensing-unit service panel to expose the contactor.
Document — Photograph all line, load, and 24V coil wiring before disconnecting anything.
Remove — Transfer wires one at a time, unscrew the contactor from its bracket, and lift it out.
Install — Mount the new contactor, reconnect each wire to its matching terminal per your photo, and confirm the shunt is intact.
Test — Restore power and call for cooling; verify the contactor pulls in and the compressor energizes.
