What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H360GKA200 — OEM 1172786 | 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 T4H360GKA200 — OEM 1172786 | 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

The OEM Tempstar 2-Pole 40A Contactor (part number 1172786) is the main switching relay for your T4H360GKA200 outdoor unit. A 24V signal from the thermostat energizes the coil, closing the 40-amp contacts to power the compressor and condenser fan. Contactors wear out from arcing, pitting, and stuck or chattering contacts — a failure that leaves the outdoor unit dead or buzzing while indoor air still moves. This is the factory 2-pole, 40A, 24V-coil contactor for a direct OEM replacement.
