What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TXA430AKA1 — 25A 24V Coil | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications.

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 single-pole definite purpose contactor (Part No. 1050699) is the electrically controlled switch that energizes the compressor and condenser fan motor in your Tempstar TXA430AKA1 condensing unit. When the thermostat calls for cooling, the 24V coil closes the contacts and sends line voltage to the compressor. Rated at 25 amps with a 24-volt control coil, this 1-pole contactor wears out over time. Pitted or burned contacts, a buzzing coil, or contacts that weld shut are classic failure symptoms that leave the unit humming but not starting, or running without shutting off.
