What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TSH530HKA100 — 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 TSH530HKA100 — 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 is the OEM definite-purpose contactor (part number 1172472) for the Tempstar TSH530HKA100 condensing unit. It is a single-pole, 30-amp device with a 24-volt control coil and an integrated shunt. The contactor is the high-voltage switch that energizes the compressor and condenser fan motor every time the thermostat calls for cooling. When the 24V coil is energized, the contacts close and pass line voltage to the outdoor unit; when the call ends, the contacts open. Because the contacts arc on each cycle, contactors are one of the most common condensing-unit failures. Typical symptoms of a failing contactor include a buzzing or chattering sound, pitted or welded contacts, a compressor that runs continuously, or an outdoor unit that will not start even though the thermostat is calling for cooling.

Compatibility

This contactor is the factory-specified replacement for the Tempstar TSH530HKA100 outdoor unit. The same 1172472 contactor is shared across many ICP-family condensing units (Tempstar, Heil, Comfortmaker, Arcoaire), so it also fits a wide range of equivalent models. Verify your existing contactor is single-pole, 30A, with a 24V coil before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and the breaker, then verify zero voltage across the line terminals with a multimeter.
Access — Remove the electrical access panel on the condensing unit.
Document — Photograph all wire connections before disconnecting anything.
Remove — Transfer the line, load, and 24V coil wires one at a time from the old contactor to the new one, then unscrew and remove the old contactor.
Install — Mount the new contactor, reconnect each wire to its matching terminal per your photo, and confirm the 24V coil leads are landed correctly.
Test — Restore power and run a cooling call; verify the contactor pulls in cleanly and the compressor and fan start.

Signs You Need a Replacement

Loud humming, buzzing, or chattering from the outdoor unit
Burned, pitted, or welded contacts
Compressor runs continuously and will not shut off (stuck closed)
