What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TCA230AKC4 — 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 is the genuine OEM single-pole contactor (part number 1050699) for the Tempstar TCA230AKC4 condensing unit. Rated 1-pole, 25 amps, with a 24V coil, the contactor is the electrical switch that delivers line voltage to the compressor and condenser fan whenever the thermostat calls for cooling. The 24V coil pulls the contacts closed to pass power, and a spring opens them when the call ends. Because the contacts arc under high current every cycle, they slowly pit, burn, and can weld shut — making the contactor one of the most common no-cooling and won't-shut-off failure points in a condensing unit.
