What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T2H336GKA100 — 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 T2H336GKA100 — 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 genuine OEM single-pole contactor (part number 1172472) is the 30-amp, 24V-coil power switch with integrated shunt for the Tempstar T2H336GKA100 heat pump. The contactor is the relay that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling or heating. Its coil pulls in a set of heavy-duty contacts that carry line voltage to the outdoor unit. After thousands of cycles, contacts pit, burn, and weld, and the 24V coil can open — leaving the outdoor unit dead while the indoor blower keeps running. A buzzing, chattering, or stuck contactor is one of the most frequent no-cool service calls.
