What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TCH624GKA100 — 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 TCH624GKA100 — 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 OEM single-pole contactor (part number 1172472) is the primary switching relay for the Tempstar TCH624GKA100 heat pump. Rated at 30 amps with a 24-volt coil and an integral shunt, it energizes the compressor and outdoor fan motor whenever the thermostat calls for cooling or heating. The contactor's electromagnetic coil pulls the contacts closed to pass line voltage to the compressor; a failed coil, pitted contacts, or welded points are among the most common reasons an outdoor unit will hum, chatter, or fail to start. Replacing a worn contactor restores reliable, clean switching and protects the compressor from low-voltage and chatter damage.

Compatibility

Engineered for the Tempstar TCH624GKA100 condensing unit and shared across many ICP-family outdoor units (Heil, Comfortmaker, Tempstar) using a 1-pole 24V control circuit. Always confirm the existing contactor's amp and coil-voltage ratings against your unit before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and verify zero voltage with a multimeter.
Access — Remove the condenser control-panel service cover.
Document — Photograph all wire positions before disconnecting anything.
Remove — Note line, load, and 24V coil terminals, then transfer wires one at a time. Unscrew the old contactor from the bracket.
Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo.
Test — Restore power and confirm the contacts pull in and the compressor/fan start on a thermostat call.
