The correct replacement for Tempstar model T2H348GKD100 — 1-Pole 30A 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.

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 1-pole definite-purpose contactor (OEM part 1172472) for the Tempstar T2H348GKD100 heat pump. Rated 30 amps with a 24-volt control coil and an integrated shunt, the contactor is the electromechanical switch that energizes the outdoor compressor and condenser fan motor whenever the thermostat calls for cooling or heating. When the 24V coil is energized, the contacts close and pass line voltage to the compressor; when the call ends, the contacts open. A worn or pitted contactor is one of the most common no-cool / no-heat failures on a heat pump. Symptoms include a buzzing or chattering outdoor unit, contacts that weld shut so the unit never shuts off, or burned/pitted contacts that prevent the compressor from starting.
