What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TXA442AKA2 — 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 TXA442AKA2 — 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 genuine OEM single-pole contactor (Part #1050699) is the 25-amp, 24-volt-coil switching relay for the Tempstar TXA442AKA2 condensing unit. When the thermostat calls for cooling, the 24V control signal energizes the coil and closes the contacts, sending line voltage to the compressor and condenser fan motor. Because the contacts arc on every cycle, contactors are a leading cause of no-cool service calls — pitted or welded contacts cause chatter, hard starts, or a unit stuck running, while a burnt-open coil stops the system from starting at all. Installing a fresh 25A contactor restores reliable switching and protects the compressor from voltage drop.
