What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T2A330GKA200 — 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 T2A330GKA200 — 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 the genuine OEM single-pole contactor (part number 1172472) for the Tempstar T2A330GKA200 condensing unit. Rated at 30 amps with a 24V coil and an integrated shunt, the contactor is the electrically operated switch that delivers high-voltage power to the compressor and condenser fan whenever the thermostat calls for cooling. Its contacts cycle thousands of times each season and gradually pit, weld, or burn. A failing contactor commonly appears as a unit that will not start, a chattering or buzzing condenser, contacts welded closed so the compressor never shuts off, or visible arcing and burnt terminals. Replacing this inexpensive, high-wear part is one of the most reliable AC repairs.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter before touching the contactor.
Access — Remove the condenser service panel to expose the control box.
Document — Photograph every line, load, and 24V coil wire before disconnecting anything.
Remove — Move the wires one at a time to the new contactor, or label and disconnect them, then unscrew the old contactor from its bracket.
Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo.
Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly with no chatter.
