What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T2A318GKD200 – 1-Pole 30A 24V 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 T2A318GKD200 – 1-Pole 30A 24V 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 genuine OEM 1-pole definite purpose contactor (Part No. 1172472) is the factory replacement for the Tempstar T2A318GKD200 condensing unit. It is rated for 30 amps with a 24-volt coil and includes an integrated shunt. The contactor acts as the high-current switch that powers the compressor and condenser fan motor each time the thermostat calls for cooling. Energizing the 24V coil closes the contacts and feeds line voltage to the outdoor unit; releasing the call opens the contacts and stops the system. Over years of cycling, the contact points pit, oxidize, and burn, which is why a worn contactor is a leading cause of an outdoor unit that hums without starting, chatters on startup, or refuses to shut off.

Compatibility

Built as the OEM-correct contactor for the Tempstar T2A318GKD200 air conditioning condenser. The same 1-pole 30A 24V contactor is widely used across ICP-family outdoor units (Heil, Comfortmaker). Confirm your existing part's amp rating, pole count, and coil voltage before installing.

Installation Guide

Safety First – Disconnect power at the outdoor disconnect and breaker, then verify zero voltage at the contactor terminals with a multimeter.
Access – Remove the condenser control panel cover to reach the contactor.
Document – Photograph all line, load, and coil wiring before disconnecting.
Remove – Label and disconnect the wires, then unbolt the old contactor from the bracket.
Install – Mount the new contactor and reconnect each wire per your photo (line in, load out, 24V to coil).
Test – Restore power and call for cooling; verify the contacts pull in and the compressor and fan run.
