What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4A348GKN200 — 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 T4A348GKN200 — 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 1-pole, 30-amp contactor with shunt (part number 1172472) is the direct replacement for the Tempstar T4A348GKN200 condensing unit. The contactor switches line voltage to the compressor and condenser fan whenever the 24V control coil is energized by a cooling call; the integrated shunt provides the correct circuit path for single-pole switching. Worn, pitted, or welded contacts and a failed coil lead to chattering, hard starts, or a system that won't run. A fresh OEM contactor restores dependable switching and safeguards your compressor.
