What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H330GKD100 — 24V Coil | 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 T4H330GKD100 — 24V Coil | 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 OEM Tempstar definite-purpose contactor (part number 1172472) is the high-voltage switch that energizes the compressor and condenser fan on the T4H330GKD100 heat pump. It is a 1-pole, 30-amp contactor with a 24V coil and an integrated shunt. When the thermostat calls, the 24V coil pulls the contacts closed and sends line voltage to the compressor; when the call ends, the contacts open. Contactors are high-wear parts — the contacts pit, burn, and weld over thousands of cycles. A failing contactor causes a unit that won't start, chatters loudly, or, when contacts weld shut, a compressor that runs nonstop and won't shut off.
