The correct replacement for Tempstar model T2H318GKD200 — 1-Pole 30A 24V w/ Shunt | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications.

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 definite purpose contactor (Tempstar part #1172472) is the electrically-controlled switch that energizes the compressor and condenser fan motor in your Tempstar T2H318GKD200 heat pump. When the thermostat calls for cooling or heating, the 24V control circuit pulls the contactor's coil in, closing the 30-amp contacts and sending line voltage to the outdoor unit. The integrated shunt provides a defined path for the high-current circuit. A failing contactor is one of the most common reasons an outdoor unit goes silent — pitted or welded contacts, a buzzing or dropped-out coil, and chattering are all classic symptoms.

Test — Restore power and call for cooling; confirm the coil pulls in cleanly and the compressor and fan start.
