What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TCH960GKA100 — 2-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 TCH960GKA100 — 2-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 power-switching relay that energizes the compressor and condenser fan on your Tempstar TCH960GKA100. A 24-volt signal from the control circuit pulls the contacts closed, delivering line voltage to the high-current components when there is a call for cooling. Over time the contacts pit, arc, and eventually weld or fail to close — producing buzzing, chattering, hard starts, or a dead outdoor unit. This 2-pole, 40 FLA contactor with a 24V coil is a direct OEM replacement that restores reliable switching.

Compatibility

Installation Guide

Safety First — Disconnect power at the breaker and the outdoor disconnect, then verify zero voltage with a multimeter across the line terminals.
Access — Remove the condensing unit service panel to expose the control box.
Document — Photograph every wire connection before disconnecting anything.
Remove — Transfer the line, load, and 24V coil leads one at a time, then unbolt the old contactor from its bracket.
Install — Mount the new contactor, move each wire to the matching terminal per your photo, and torque connections snug.
Test — Restore power, call for cooling, and confirm the contacts pull in cleanly with no chatter.

Signs You Need a Replacement
