What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4A624GKD200 — 24V Coil with 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 OEM Tempstar contactor (part number 1172472) is a single-pole (1P), 30-amp electrical switch with a 24-volt control coil and integrated shunt. The contactor is the heart of your condensing unit's electrical system — when the thermostat calls for cooling, the 24V signal energizes the coil, pulling the contacts closed to deliver line voltage to the compressor and condenser fan motor. The built-in shunt provides a return path for low-voltage components. Over time, the contact points pit, burn, or weld from constant arcing, and the coil can fail. A failing contactor causes the outdoor unit to not start, to buzz or chatter, or to run continuously even after the thermostat is satisfied.

Installation Guide

Remove — Note line, load, and 24V coil terminal locations, transfer wires one at a time, and unscrew the old contactor from the bracket.

Test — Restore power and confirm the contactor pulls in on a cooling call and the unit starts normally.
