What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H324GKD200 — OEM 1172472 | 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 OEM 1-pole, 30-amp contactor with shunt (part number 1172472) is the high-voltage switch that powers the compressor and outdoor fan on your Tempstar T4H324GKD200. When the thermostat calls for cooling or heating, the contactor's 24V coil pulls the contacts closed, sending line voltage to the compressor and condenser fan motor. Over time the silver contacts pit, burn, or weld from arcing, and the coil can fail to pull in. Symptoms of a bad contactor include an outdoor unit that hums but won't start, contacts that chatter or stick closed (so the unit won't shut off), and visible pitting or scorching on the contact points. The integrated shunt provides the factory-correct power path for this platform.
