What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H436GKC200 — OEM 1172472 | 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 30 Amp 24V Contactor with shunt (part number 1172472) for the Tempstar T4H436GKC200. The contactor is an electrically operated switch: a 24V signal from the thermostat/control board energizes the coil, pulling the contacts closed to deliver line voltage to the compressor and condenser fan motor. The integrated shunt provides a continuous path for one leg. Contactors are high-wear parts — their contacts pit and burn from arcing over thousands of cycles, eventually welding shut (compressor won't shut off) or failing to close (system won't start).
