What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4A424GKA200 – 1-Pole 30A 24V | 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 is the genuine OEM single-pole definite-purpose contactor (part #1172472) for the Tempstar T4A424GKA200 condensing unit. It is rated for 30 amps with a 24-volt control coil and includes the factory shunt. The contactor acts as the high-voltage switch that powers the compressor and condenser fan whenever the thermostat calls for cooling — the 24V coil pulls the contacts closed to pass line voltage to the load. Contactors wear out from pitted or welded contacts, a failed coil, or debris intrusion, which can leave the outdoor unit dead or cause loud chattering. Replacing a worn contactor restores reliable starting and prevents the contact bounce that shortens compressor life.

Compatibility

Direct-fit OEM replacement for the Tempstar T4A424GKA200 condenser. Shared across related ICP/Heil/Comfortmaker single-stage condensing units using the same 30A 24V single-pole contactor. Confirm your existing part is stamped 1172472 and that your control circuit is 24V before installing.

Installation Guide

Safety First – Disconnect power at the outdoor disconnect and verify zero voltage on the line terminals with a multimeter.
Access – Remove the condenser electrical access panel.
Document – Photograph every wire on the line, load, and coil terminals before disconnecting.
Remove – Transfer or label the wires, then unbolt the old contactor from its mounting bracket.
Install – Mount the new contactor, land the line, load, and 24V coil wires per your photo, and verify the shunt is in place.
Test – Restore power, call for cooling, and confirm the contacts pull in cleanly with no chatter and the compressor and fan energize.

Signs You Need a Replacement
