What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TCA960GKA100 — 1-Pole 24V Coil | 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 TCA960GKA100 — 1-Pole 24V Coil | 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 definite purpose contactor (part number 1176763) is the high-current switch that powers the compressor and condenser fan motor in the Tempstar TCA960GKA100. When the thermostat calls for cooling, the 24-volt control coil energizes and pulls the line-voltage contacts closed. Rated at 40 amps in a 1-pole configuration with a 24V coil, it is designed for thousands of reliable switching cycles. Contactors are a leading cause of no-cooling service calls: contacts pit, burn, or weld over time, and the coil can fail open or chatter. Symptoms include a unit that buzzes but won't start, a system that runs nonstop because the contacts are welded shut, or intermittent cooling. A new contactor restores clean, dependable switching.
