What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TXA242AKA2 — 1-Pole 25A 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.

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 genuine OEM single-pole definite purpose contactor (part number 1050699) is the direct replacement switch for the Tempstar TXA242AKA2 condensing unit. Rated at 25 amps with a 24-volt control coil, the contactor closes its contacts when the thermostat calls for cooling, sending line voltage to the compressor and condenser fan motor. Every cooling cycle drives high inrush current across these contacts, so over time they pit, burn, and eventually weld or fail open. Typical failure symptoms include an outdoor unit that hums but will not start, a compressor that keeps running after the call for cooling ends, chattering at the contactor, or scorch marks on the terminals. It is one of the most common and least expensive parts to keep an AC or heat pump running reliably.
