What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TXA661GKA100 — 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 TXA661GKA100 — 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 contactor (part 1176763) is the heavy-duty line-voltage switch for the Tempstar TXA661GKA100 condensing unit. A 24V coil closes the high-current contacts to power the compressor and condenser fan motor. The higher 40A rating handles the larger inrush of this unit's compressor. Contactors are a top wear item: the contacts arc and pit on every cycle, and the coil can fail open. A bad contactor shows up as a chattering unit, a no-start condition, or a system that runs nonstop because the contacts have welded shut.
