What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H330GKD200 — 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 T4H330GKD200 — 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 genuine OEM single-pole contactor with shunt (part number 1172472) switches high-voltage power to the compressor and condenser fan on the Tempstar T4H330GKD200 heat pump. Rated at 30 amps with a 24V control coil, the contactor pulls in when the thermostat calls and energizes the outdoor unit. The shunt provides a controlled path for the integrated capacitor/control circuit. Contactors fail from pitted or welded contacts, a burned-out coil, or insect/debris fouling — leaving the unit dead, chattering, or stuck running even after the call ends. Common symptoms include a humming contactor that will not pull in, visible arcing or burnt contacts, or a compressor that runs continuously.
