What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4A348GKD200 — 30A 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.

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 is a genuine OEM single-pole definite purpose contactor (part #1172472) for the Tempstar T4A348GKD200 condensing unit. The contactor is the electromechanical switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. When the 24V control coil is energized, the contactor pulls in and closes the line-voltage contacts to start the system. This unit is rated for 30 amps with a 24V coil and includes an auxiliary shunt. Common failure symptoms include a unit that won't start, chattering or buzzing at the contactor, pitted or welded contacts, and a compressor that runs even after the call for cooling ends.
