What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TSA660GKA100 — 40A Definite Purpose | 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 TSA660GKA100 — 40A Definite Purpose | 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 OEM 40-amp contactor (part number 1176763) is the main switching relay for the Tempstar TSA660GKA100 condensing unit. Rated at 40 amps with a 24-volt control coil, it carries the higher running current of this larger-capacity system and energizes the compressor and condenser fan on every cooling call. As the contacts carry full load current cycle after cycle, they pit and erode; a worn contactor causes the unit to fail to start, buzz loudly, or weld closed so the compressor never shuts off. A 40A contactor should always be replaced with a 40A unit — using an undersized contactor leads to premature failure.
