What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T2A348GKD100 — OEM with 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 T2A348GKD100 — OEM with 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 OEM 1-pole 30-amp definite-purpose contactor with shunt (part number 1172472) is the switching relay that energizes the compressor and condenser fan on the Tempstar T2A348GKD100. A 24V control signal from the thermostat pulls in the contactor coil, closing the 30A line-voltage contacts. Pitted, welded, or chattering contacts are a leading cause of no-cool calls, hard starts, and burnt control wiring.
