What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TCA236VKA1 — 1-Pole 25A 24V | 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 a genuine OEM single-pole definite purpose contactor (part #1050699) for the Tempstar TCA236VKA1 condensing unit. The contactor is the electrically operated switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. A 24V control signal pulls in the coil, closing the line-voltage contacts that carry power to the outdoor unit. Rated for 25 amps with a 24-volt coil, this 1-pole contactor handles the switching load for residential single-phase systems. Common failure symptoms include pitted or welded contacts, a buzzing or chattering coil, the outdoor unit not starting on a cooling call, or the compressor and fan continuing to run after the call ends.

Compatibility

Remove — Transfer wires one at a time, or label them, then unscrew the old contactor from the bracket.
Install — Mount the new contactor, reconnect line, load, and 24V coil leads exactly per your photo.
Test — Restore power, call for cooling, and confirm the coil pulls in cleanly and the unit starts.
