What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T2A324GKD100 — 1-Pole 30A 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. You can verify this by checking the data plate on your Tempstar equipment which lists the model number T2A324GKD100 — 1-Pole 30A 24V Coil with 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 genuine OEM single-pole contactor (part #1172472) is the factory-specified power switch for the Tempstar T2A324GKD100 condensing unit. The contactor uses a 24V control coil to close a 30-amp line-voltage contact set, energizing the compressor and condenser fan motor on every call for cooling. The integrated shunt provides the auxiliary connection point used on this ICP platform. Contactors are wear items — their contacts arc each time they open and close — so pitting, welding, and a weakening coil are among the most common causes of no-cooling and won't-shut-off service calls.

Compatibility

Verify the amp rating, pole count, and 24V coil voltage of your existing contactor before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker. Verify zero voltage at the contactor terminals with a multimeter.
Access — Remove the electrical access panel on the condensing unit.
Document — Photograph all wire connections, including line, load, coil, and shunt terminals, before disconnecting.
Remove — Disconnect each lead, unfasten the contactor from its bracket, and lift it out.
Install — Mount the new contactor in the same orientation and reconnect every wire per your photo.
Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the unit starts without chatter.
