What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T2A348GKD200 — 24V Coil 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 T2A348GKD200 — 24V Coil 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 definite purpose contactor with shunt (Part Number 1172472) for the Tempstar T2A348GKD200 condensing unit. The contactor is an electrically controlled switch that uses a 24-volt control signal from your thermostat to energize the high-voltage circuit feeding the compressor and condenser fan motor. Rated at 30 amps with a 24V coil, the single-pole design switches one line leg while the shunt maintains the constant leg, making it a compact and economical switching device for the outdoor unit. When the contactor fails, the most common symptoms are an outdoor unit that will not start, a humming or chattering noise from the control box, pitted or burned contact points, or a system that runs continuously because the contacts have welded shut. Replacing a worn contactor is one of the most common and inexpensive HVAC repairs.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter.
Access — Remove the service panel on the condensing unit to expose the control box.
Document — Photograph all wire connections before disconnecting anything.
Remove — Note the line, load, shunt, 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 per your photo, ensuring the shunt leg is wired correctly.
Test — Restore power and confirm the contactor pulls in and the unit starts on a cooling call.
