What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TXA660GKA100 — 24V Coil Condenser Contactor | 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 TXA660GKA100 — 24V Coil Condenser Contactor | 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 primary switching relay for the Tempstar TXA660GKA100 condensing unit. When the thermostat calls for cooling, the 24-volt control circuit energizes the contactor coil, which pulls the contacts closed and sends line voltage to the compressor and condenser fan motor. Rated at 40A with a 24V coil, it carries the full inrush and running current of the outdoor unit. Common failure symptoms include a unit that hums but won't start, pitted or welded contacts, chattering, or an outdoor unit that runs continuously because the contacts are stuck closed. A worn contactor is one of the most frequent causes of no-cooling service calls.

Compatibility

Engineered as a direct OEM replacement for the Tempstar TXA660GKA100 condensing unit. This contactor is also used across many ICP-family outdoor units (Heil, Comfortmaker, Tempstar) that share the same 40A 24V coil specification. Always confirm your existing contactor's amp rating, pole count, and coil voltage match before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker; verify zero voltage with a multimeter at the contactor terminals.
Access — Remove the condenser service panel to expose the contactor.
Document — Photograph all wire connections before disconnecting anything.
Remove — Label and disconnect line, load, and 24V coil wires; unscrew the old contactor from the mounting bracket.
Install — Mount the new contactor, then reconnect each wire per your photo (line in, compressor/fan out, 24V to coil terminals).
Test — Restore power and call for cooling; confirm the contacts pull in cleanly and the compressor and fan start.
